Agenda aims to keep its code base small. - Mongo backed persistence layer. - Scheduling with configurable priority, concurrency, and repeating - Scheduling via cron or human readable syntax. - Event backed job queue that you can hook into. - [Agendash](https://github.com/agenda/agendash): optional standalone web-interface # Installation Install via NPM npm install agenda You will also need a working [Mongo](https://www.mongodb.com/) database (2.6+) to point it to. # Example Usage ```js var mongoConnectionString = 'mongodb://127.0.0.1/agenda'; var agenda = new Agenda({db: {address: mongoConnectionString}}); // or override the default collection name: // var agenda = new Agenda({db: {address: mongoConnectionString, collection: 'jobCollectionName'}}); // or pass additional connection options: // var agenda = new Agenda({db: {address: mongoConnectionString, collection: 'jobCollectionName', options: {ssl: true}}}); // or pass in an existing mongodb-native MongoClient instance // var agenda = new Agenda({mongo: myMongoClient}); agenda.define('delete old users', function(job, done) { User.remove({lastLogIn: { $lt: twoDaysAgo }}, done); }); agenda.on('ready', function() { agenda.every('3 minutes', 'delete old users'); // Alternatively, you could also do: agenda.every('*/3 * * * *', 'delete old users'); agenda.start(); }); ``` ```js agenda.define('send email report', {priority: 'high', concurrency: 10}, function(job, done) { var data = job.attrs.data; emailClient.send({ to: data.to, from: 'example@example.com', subject: 'Email Report', body: '...' }, done); }); agenda.on('ready', function() { agenda.schedule('in 20 minutes', 'send email report', {to: 'admin@example.com'}); agenda.start(); }); ``` ```js agenda.on('ready', function() { var weeklyReport = agenda.create('send email report', {to: 'another-guy@example.com'}) weeklyReport.repeatEvery('1 week').save(); agenda.start(); }); ``` # Full documentation Agenda's basic control structure is an instance of an agenda. Agenda's are mapped to a database collection and load the jobs from within. ## Table of Contents - [Configuring an agenda](#configuring-an-agenda) - [Agenda Events](#agenda-events) - [Defining job processors](#defining-job-processors) - [Creating jobs](#creating-jobs) - [Managing jobs](#managing-jobs) - [Starting the job processor](#starting-the-job-processor) - [Multiple job processors](#multiple-job-processors) - [Manually working with jobs](#manually-working-with-a-job) - [Job Queue Events](#job-queue-events) - [Frequently asked questions](#frequently-asked-questions) - [Example Project structure](#example-project-structure) - [Known Issues](#known-issues) - [Debugging Issues](#debugging-issues) - [Acknowledgements](#acknowledgements) ## Configuring an agenda All configuration methods are chainable, meaning you can do something like: ```js var agenda = new Agenda(); agenda .database(...) .processEvery('3 minutes') ...; ``` Agenda uses [Human Interval](http://github.com/rschmukler/human-interval) for specifying the intervals. It supports the following units: `seconds`, `minutes`, `hours`, `days`,`weeks`, `months` -- assumes 30 days, `years` -- assumes 365 days More sophisticated examples ```js agenda.processEvery('one minute'); agenda.processEvery('1.5 minutes'); agenda.processEvery('3 days and 4 hours'); agenda.processEvery('3 days, 4 hours and 36 seconds'); ``` ### database(url, [collectionName]) Specifies the database at the `url` specified. If no collection name is given, `agendaJobs` is used. ```js agenda.database('localhost:27017/agenda-test', 'agendaJobs'); ``` You can also specify it during instantiation. ```js var agenda = new Agenda({db: { address: 'localhost:27017/agenda-test', collection: 'agendaJobs' }}); ``` Agenda will emit a `ready` event (see [Agenda Events](#agenda-events)) when properly connected to the database and it is safe to start using Agenda. ### mongo(mongoClientInstance) Use an existing mongodb-native MongoClient instance. This can help consolidate connections to a database. You can instead use `.database` to have agenda handle connecting for you. Please note that this must be a *collection*. Also, you will want to run the following afterwards to ensure the database has the proper indexes: ```js function ignoreErrors() {} agenda._db.ensureIndex('nextRunAt', ignoreErrors) .ensureIndex('lockedAt', ignoreErrors) .ensureIndex('name', ignoreErrors) .ensureIndex('priority', ignoreErrors); function ignoreErrors ``` You can also specify it during instantiation. ```js var agenda = new Agenda({mongo: mongoClientInstance}); ``` ### name(name) Takes a string `name` and sets `lastModifiedBy` to it in the job database. Useful for if you have multiple job processors (agendas) and want to see which job queue last ran the job. ```js agenda.name(os.hostname + '-' + process.pid); ``` You can also specify it during instantiation ```js var agenda = new Agenda({name: 'test queue'}); ``` ### processEvery(interval) Takes a string `interval` which can be either a traditional javascript number, or a string such as `3 minutes` Specifies the frequency at which agenda will query the database looking for jobs that need to be processed. Agenda internally uses `setTimeout` to guarantee that jobs run at (close to ~3ms) the right time. Decreasing the frequency will result in fewer database queries, but more jobs being stored in memory. Also worth noting is that if the job queue is shutdown, any jobs stored in memory that haven't run will still be locked, meaning that you may have to wait for the lock to expire. ```js agenda.processEvery('1 minute'); ``` You can also specify it during instantiation ```js var agenda = new Agenda({processEvery: '30 seconds'}); ``` ### maxConcurrency(number) Takes a `number` which specifies the max number of jobs that can be running at any given moment. By default it is `20`. ```js agenda.maxConcurrency(20); ``` You can also specify it during instantiation ```js var agenda = new Agenda({maxConcurrency: 20}); ``` ### defaultConcurrency(number) Takes a `number` which specifies the default number of a specific job that can be running at any given moment. By default it is `5`. ```js agenda.defaultConcurrency(5); ``` You can also specify it during instantiation ```js var agenda = new Agenda({defaultConcurrency: 5}); ``` ### lockLimit(number) Takes a `number` which specifies the max number jobs that can be locked at any given moment. By default it is `0` for no max. ```js agenda.lockLimit(0); ``` You can also specify it during instantiation ```js var agenda = new Agenda({lockLimit: 0}); ``` ### defaultLockLimit(number) Takes a `number` which specifies the default number of a specific job that can be locked at any given moment. By default it is `0` for no max. ```js agenda.defaultLockLimit(0); ``` You can also specify it during instantiation ```js var agenda = new Agenda({defaultLockLimit: 0}); ``` ### defaultLockLifetime(number) Takes a `number` which specifies the default lock lifetime in milliseconds. By default it is 10 minutes. This can be overridden by specifying the `lockLifetime` option to a defined job. A job will unlock if it is finished (ie. `done` is called) before the `lockLifetime`. The lock is useful if the job crashes or times out. ```js agenda.defaultLockLifetime(10000); ``` You can also specify it during instantiation ```js var agenda = new Agenda({defaultLockLifetime: 10000}); ``` ### sort(query) Takes a `query` which specifies the sort query to be used for finding and locking the next job. By default it is `{ nextRunAt: 1, priority: -1 }`, which obeys a first in first out approach, with respect to priority. ## Agenda Events An instance of an agenda will emit the following events: - `ready` - called when Agenda mongo connection is successfully opened - `error` - called when Agenda mongo connection process has thrown an error ```js agenda.on('ready', function() { agenda.start(); }); ``` ## Defining Job Processors Before you can use a job, you must define its processing behavior. ### define(jobName, [options], fn) Defines a job with the name of `jobName`. When a job of `jobName` gets run, it will be passed to `fn(job, done)`. To maintain asynchronous behavior, you must call `done()` when you are processing the job. If your function is synchronous, you may omit `done` from the signature. `options` is an optional argument which can overwrite the defaults. It can take the following: - `concurrency`: `number` maximum number of that job that can be running at once (per instance of agenda) - `lockLimit`: `number` maximum number of that job that can be locked at once (per instance of agenda) - `lockLifetime`: `number` interval in ms of how long the job stays locked for (see [multiple job processors](#multiple-job-processors) for more info). A job will automatically unlock if `done()` is called. - `priority`: `(lowest|low|normal|high|highest|number)` specifies the priority of the job. Higher priority jobs will run first. See the priority mapping below Priority mapping: ``` { highest: 20, high: 10, default: 0, low: -10, lowest: -20 } ``` Async Job: ```js agenda.define('some long running job', function(job, done) { doSomelengthyTask(function(data) { formatThatData(data); sendThatData(data); done(); }); }); ``` Sync Job: ```js agenda.define('say hello', function(job) { console.log('Hello!'); }); ``` ## Creating Jobs ### every(interval, name, [data], [options], [cb]) Runs job `name` at the given `interval`. Optionally, data and options can be passed in. Every creates a job of type `single`, which means that it will only create one job in the database, even if that line is run multiple times. This lets you put it in a file that may get run multiple times, such as `webserver.js` which may reboot from time to time. `interval` can be a human-readable format `String`, a cron format `String`, or a `Number`. `data` is an optional argument that will be passed to the processing function under `job.attrs.data`. `options` is an optional argument that will be passed to `job.repeatEvery`. In order to use this argument, `data` must also be specified. `cb` is an optional callback function which will be called when the job has been persisted in the database. Returns the `job`. ```js agenda.define('printAnalyticsReport', function(job, done) { User.doSomethingReallyIntensive(function(err, users) { processUserData(); console.log('I print a report!'); done(); }); }); agenda.every('15 minutes', 'printAnalyticsReport'); ``` Optionally, `name` could be array of job names, which is convenient for scheduling different jobs for same `interval`. ```js agenda.every('15 minutes', ['printAnalyticsReport', 'sendNotifications', 'updateUserRecords']); ``` In this case, `every` returns array of `jobs`. ### schedule(when, name, [data], [cb]) Schedules a job to run `name` once at a given time. `when` can be a `Date` or a `String` such as `tomorrow at 5pm`. `data` is an optional argument that will be passed to the processing function under `job.attrs.data`. `cb` is an optional callback function which will be called when the job has been persisted in the database. Returns the `job`. ```js agenda.schedule('tomorrow at noon', 'printAnalyticsReport', {userCount: 100}); ``` Optionally, `name` could be array of job names, similar to `every` method. ```js agenda.schedule('tomorrow at noon', ['printAnalyticsReport', 'sendNotifications', 'updateUserRecords']); ``` In this case, `schedule` returns array of `jobs`. ### now(name, [data], [cb]) Schedules a job to run `name` once immediately. `data` is an optional argument that will be passed to the processing function under `job.attrs.data`. `cb` is an optional callback function which will be called when the job has been persisted in the database. Returns the `job`. ```js agenda.now('do the hokey pokey'); ``` ### create(jobName, data) Returns an instance of a `jobName` with `data`. This does *NOT* save the job in the database. See below to learn how to manually work with jobs. ```js var job = agenda.create('printAnalyticsReport', {userCount: 100}); job.save(function(err) { console.log('Job successfully saved'); }); ``` ## Managing Jobs ### jobs(mongodb-native query) Lets you query all of the jobs in the agenda job's database. This is a full [mongodb-native](https://github.com/mongodb/node-mongodb-native) `find` query. See mongodb-native's documentation for details. ```js agenda.jobs({name: 'printAnalyticsReport'}, function(err, jobs) { // Work with jobs (see below) }); ``` ### cancel(mongodb-native query, cb) Cancels any jobs matching the passed mongodb-native query, and removes them from the database. ```js agenda.cancel({name: 'printAnalyticsReport'}, function(err, numRemoved) { }); ``` This functionality can also be achieved by first retrieving all the jobs from the database using `agenda.jobs()`, looping through the resulting array and calling `job.remove()` on each. It is however preferable to use `agenda.cancel()` for this use case, as this ensures the operation is atomic. ### purge(cb) Removes all jobs in the database without defined behaviors. Useful if you change a definition name and want to remove old jobs. *IMPORTANT:* Do not run this before you finish defining all of your jobs. If you do, you will nuke your database of jobs. ```js agenda.purge(function(err, numRemoved) { }); ``` ## Starting the job processor To get agenda to start processing jobs from the database you must start it. This will schedule an interval (based on `processEvery`) to check for new jobs and run them. You can also stop the queue. ### start Starts the job queue processing, checking `processEvery` time to see if there are new jobs. ### stop Stops the job queue processing. Unlocks currently running jobs. This can be very useful for graceful shutdowns so that currently running/grabbed jobs are abandoned so that other job queues can grab them / they are unlocked should the job queue start again. Here is an example of how to do a graceful shutdown. ```js function graceful() { agenda.stop(function() { process.exit(0); }); } process.on('SIGTERM', graceful); process.on('SIGINT' , graceful); ``` ## Multiple job processors Sometimes you may want to have multiple node instances / machines process from the same queue. Agenda supports a locking mechanism to ensure that multiple queues don't process the same job. You can configure the locking mechanism by specifying `lockLifetime` as an interval when defining the job. ```js agenda.define('someJob', {lockLifetime: 10000}, function(job, cb) { //Do something in 10 seconds or less... }); ``` This will ensure that no other job processor (this one included) attempts to run the job again for the next 10 seconds. If you have a particularly long running job, you will want to specify a longer lockLifetime. By default it is 10 minutes. Typically you shouldn't have a job that runs for 10 minutes, so this is really insurance should the job queue crash before the job is unlocked. When a job is finished (ie. `done` is called), it will automatically unlock. ## Manually working with a job A job instance has many instance methods. All mutating methods must be followed with a call to `job.save()` in order to persist the changes to the database. ### repeatEvery(interval, [options]) Specifies an `interval` on which the job should repeat. `interval` can be a human-readable format `String`, a cron format `String`, or a `Number`. `options` is an optional argument that can include a `timezone` field. The timezone should be a string as accepted by [moment-timezone](http://momentjs.com/timezone/) and is considered when using an interval in the cron string format. ```js job.repeatEvery('10 minutes'); job.save(); ``` ```js job.repeatEvery('0 6 * * *', { timezone: 'America/New_York' }); job.save(); ``` ### repeatAt(time) Specifies a `time` when the job should repeat. [Possible values](https://github.com/matthewmueller/date#examples) ```js job.repeatAt('3:30pm'); job.save(); ``` ### schedule(time) Specifies the next `time` at which the job should run. ```js job.schedule('tomorrow at 6pm'); job.save(); ``` ### priority(priority) Specifies the `priority` weighting of the job. Can be a number or a string from the above priority table. ```js job.priority('low'); job.save(); ``` ### unique(properties, [options]) Ensure that only one instance of this job exists with the specified properties `options` is an optional argument which can overwrite the defaults. It can take the following: - `insertOnly`: `boolean` will prevent any properties from persisting if job already exists. Defaults to false. ```js job.unique({'data.type': 'active', 'data.userId': '123', nextRunAt(date)}); job.save(); ``` *IMPORTANT:* To avoid high CPU usage by MongoDB, Make sure to create an index on the used fields, like: `data.type` and `data.userId` for the example above. ### fail(reason) Sets `job.attrs.failedAt` to `now`, and sets `job.attrs.failReason` to `reason`. Optionally, `reason` can be an error, in which case `job.attrs.failReason` will be set to `error.message` ```js job.fail('insuficient disk space'); // or job.fail(new Error('insufficient disk space')); job.save(); ``` ### run(callback) Runs the given `job` and calls `callback(err, job)` upon completion. Normally you never need to call this manually. ```js job.run(function(err, job) { console.log('I don\'t know why you would need to do this...'); }); ``` ### save(callback) Saves the `job.attrs` into the database. ```js job.save(function(err) { if(!err) console.log('Successfully saved job to collection'); }) ``` ### remove(callback) Removes the `job` from the database. ```js job.remove(function(err) { if(!err) console.log('Successfully removed job from collection'); }) ``` ### disable() Disables the `job`. Upcoming runs won't execute. ### enable() Enables the `job` if it got disabled before. Upcoming runs will execute. ### touch(callback) Resets the lock on the job. Useful to indicate that the job hasn't timed out when you have very long running jobs. ```js agenda.define('super long job', function(job, done) { doSomeLongTask(function() { job.touch(function() { doAnotherLongTask(function() { job.touch(function() { finishOurLongTasks(done); }); }); }); }); }); ``` ## Job Queue Events An instance of an agenda will emit the following events: - `start` - called just before a job starts - `start:job name` - called just before the specified job starts ```js agenda.on('start', function(job) { console.log('Job %s starting', job.attrs.name); }); ``` - `complete` - called when a job finishes, regardless of if it succeeds or fails - `complete:job name` - called when a job finishes, regardless of if it succeeds or fails ```js agenda.on('complete', function(job) { console.log('Job %s finished', job.attrs.name); }); ``` - `success` - called when a job finishes successfully - `success:job name` - called when a job finishes successfully ```js agenda.on('success:send email', function(job) { console.log('Sent Email Successfully to: %s', job.attrs.data.to); }); ``` - `fail` - called when a job throws an error - `fail:job name` - called when a job throws an error ```js agenda.on('fail:send email', function(err, job) { console.log('Job failed with error: %s', err.message); }); ``` ## Frequently Asked Questions ### What is the order in which jobs run? Jobs are run with priority in a first in first out order (so they will be run in the order they were scheduled AND with respect to highest priority). For example, if we have two jobs named "send-email" queued (both with the same priority), and the first job is queued at 3:00 PM and second job is queued at 3:05 PM with the same `priority` value, then the first job will run first if we start to send "send-email" jobs at 3:10 PM. However if the first job has a priority of `5` and the second job has a priority of `10`, then the second will run first (priority takes precedence) at 3:10 PM. The default [MongoDB sort object](https://docs.mongodb.com/manual/reference/method/cursor.sort/) is `{ nextRunAt: 1, priority: -1 }` and can be changed through the option `sort` when configuring Agenda. ### Sample Project Structure? Agenda doesn't have a preferred project structure and leaves it to the user to choose how they would like to use it. That being said, you can check out the [example project structure](#example-project-structure) below. ### Can I Donate? Thanks! I'm flattered, but it's really not necessary. If you really want to, you can find my [gittip here](https://www.gittip.com/rschmukler/). ### Web Interface? Agenda itself does not have a web interface built in but we do offer stand-alone web interface [Agendash](https://github.com/agenda/agendash): ![agendash interface](https://raw.githubusercontent.com/agenda/agendash/master/job-details.png) ### Mongo vs Redis The decision to use Mongo instead of Redis is intentional. Redis is often used for non-essential data (such as sessions) and without configuration doesn't guarantee the same level of persistence as Mongo (should the server need to be restarted/crash). Agenda decides to focus on persistence without requiring special configuration of Redis (thereby degrading the performance of the Redis server on non-critical data, such as sessions). Ultimately if enough people want a Redis driver instead of Mongo, I will write one. (Please open an issue requesting it). For now, Agenda decided to focus on guaranteed persistence. ### Spawning / forking processes. Ultimately Agenda can work from a single job queue across multiple machines, node processes, or forks. If you are interested in having more than one worker, [Bars3s](http://github.com/bars3s) has written up a fantastic example of how one might do it: ```js var cluster = require('cluster'), cpuCount = require('os').cpus().length, jobWorkers = [], webWorkers = []; if (cluster.isMaster) { // Create a worker for each CPU for (var i = 0; i < cpuCount; i += 1) { addJobWorker(); addWebWorker(); } cluster.on('exit', function (worker, code, signal) { if (jobWorkers.indexOf(worker.id) != -1) { console.log('job worker ' + worker.process.pid + ' died. Trying to respawn...'); removeJobWorker(worker.id); addJobWorker(); } if (webWorkers.indexOf(worker.id) != -1) { console.log('http worker ' + worker.process.pid + ' died. Trying to respawn...'); removeWebWorker(worker.id); addWebWorker(); } }); } else { if (process.env.web) { console.log('start http server: ' + cluster.worker.id); require('./app/web-http');//initialize the http server here } if (process.env.job) { console.log('start job server: ' + cluster.worker.id); require('./app/job-worker');//initialize the agenda here } } function addWebWorker() { webWorkers.push(cluster.fork({web: 1}).id); } function addJobWorker() { jobWorkers.push(cluster.fork({job: 1}).id); } function removeWebWorker(id) { webWorkers.splice(webWorkers.indexOf(id), 1); } function removeJobWorker(id) { jobWorkers.splice(jobWorkers.indexOf(id), 1); } ``` ### Recovering lost Mongo connections ("auto_reconnect") Agenda is configured by default to automatically reconnect indefinitely, emitting an [error event](#agenda-events) when no connection is available on each [process tick](#processeveryinterval), allowing you to restore the Mongo instance without having to restart the application. However, if you are using an [existing Mongo client](#mongomongoclientinstance) you'll need to configure the `reconnectTries` and `reconnectInterval` [connection settings](http://mongodb.github.io/node-mongodb-native/2.2/reference/connecting/connection-settings/) manually, otherwise you'll find that Agenda will throw an error with the message "MongoDB connection is not recoverable, application restart required" if the connection cannot be recovered within 30 seconds. # Example Project Structure Agenda will only process jobs that it has definitions for. This allows you to selectively choose which jobs a given agenda will process. Consider the following project structure, which allows us to share models with the rest of our code base, and specify which jobs a worker processes, if any at all. ``` - server.js - worker.js lib/ - agenda.js controllers/ - user-controller.js jobs/ - email.js - video-processing.js - image-processing.js models/ - user-model.js - blog-post.model.js ``` Sample job processor (eg. `jobs/email.js`) ```js var email = require('some-email-lib'), User = require('../models/user-model.js'); module.exports = function(agenda) { agenda.define('registration email', function(job, done) { User.get(job.attrs.data.userId, function(err, user) { if(err) return done(err); email(user.email(), 'Thanks for registering', 'Thanks for registering ' + user.name(), done); }); }); agenda.define('reset password', function(job, done) { // etc etc }) // More email related jobs } ``` lib/agenda.js ```js var Agenda = require('agenda'); var agenda = new Agenda(connectionOpts); var jobTypes = process.env.JOB_TYPES ? process.env.JOB_TYPES.split(',') : []; jobTypes.forEach(function(type) { require('./lib/jobs/' + type)(agenda); }) if(jobTypes.length) { agenda.start(); } module.exports = agenda; ``` lib/controllers/user-controller.js ```js var app = express(), User = require('../models/user-model'), agenda = require('../worker.js'); app.post('/users', function(req, res, next) { var user = new User(req.body); user.save(function(err) { if(err) return next(err); agenda.now('registration email', { userId: user.primary() }); res.send(201, user.toJson()); }); }); ``` worker.js ```js require('./lib/agenda.js'); ``` Now you can do the following in your project: ``` node server.js ``` Fire up an instance with no `JOB_TYPES`, giving you the ability to process jobs, but not wasting resources processing jobs. ``` JOB_TYPES=email node server.js ``` Allow your http server to process email jobs. ``` JOB_TYPES=email node worker.js ``` Fire up an instance that processes email jobs. ``` JOB_TYPES=video-processing,image-processing node worker.js ``` Fire up an instance that processes video-processing/image-processing jobs. Good for a heavy hitting server. # Known Issues ## Versions <= 0.9.1 #### Cron string parsing ([PR](https://github.com/agenda/agenda/pull/475)) The current versions of Agenda parse cron dates as follows using this library: [node-cron](https://github.com/kelektiv/node-cron) _This library treats months as 0-11 where as normally, cron months are parsed as 1-12._ ``` * * * * * * | | | | | | | | | | | +-- Year (range: 1900-3000) | | | | +---- Day of the Week (range: 1-7, 1 standing for Monday) | | | +------ Month of the Year (range: 0-11) NOTE: Difference here | | +-------- Day of the Month (range: 1-31) | +---------- Hour (range: 0-23) +------------ Minute (range: 0-59) ``` Starting in version `1.0.0`, cron will be parsed in the standard UNIX style: ``` * * * * * * | | | | | | | | | | | +-- Year (range: 1900-3000) | | | | +---- Day of the Week (range: 1-7, 1 standing for Monday) | | | +------ Month of the Year (range: 1-12) NOTE: Difference here | | +-------- Day of the Month (range: 1-31) | +---------- Hour (range: 0-23) +------------ Minute (range: 0-59) ``` # Debugging Issues If you think you have encountered a bug, please feel free to report it here: [Submit Issue](https://github.com/agenda/agenda/issues/new) Please provide us with as much details as possible such as: - Agenda version - Environment (OSX, Linux, Windows, etc) - Small description of what happened - Any relevant stack track - Agenda logs (see below) #### To turn on logging, please set your DEBUG env variable like so: - OSX: `DEBUG="agenda:*" node index.js` - Linux: `DEBUG="agenda:*" node index.js` - Windows CMD: `set DEBUG=agenda:*` - Windows PowerShell: `$env:DEBUG = "agenda:*"` While not necessary, attaching a text file with this debug information would be extremely useful in debugging certain issues and is encouraged. # Acknowledgements - Agenda was originally created by [@rschmukler](https://github.com/rschmukler). - [Agendash](https://github.com/agenda/agendash) was originally created by [@joeframbach](https://github.com/joeframbach). - These days Agenda has a great community of [contributors](https://github.com/agenda/agenda/graphs/contributors) around it.
