A platform to build backened code mostly in a visual manner.

const fs = require('fs');
const path = require('path');

const platform = require('../../');
const config = require('./config');
const files = require('./util/file-io');

  path : `${config.path}delete/:id`,
  public : config.expose,
  method : 'DELETE',
  inputs : ['id'],
  controlOutputs : ['deleted', 'no_directory_set', 'internal_error'],
}, (inputs, _, control) => {
  if (!config.directory)
    control('no_directory_set');

  let pathmapfile = path.join(config.directory, config.files.pathmap);

  files.json.load(pathmapfile, {})
    .then(pathmap => {
      let paths = Object.entries(pathmap)
            .filter(entry => entry[1] == inputs.id)
            .map(entry => entry[0])
            .forEach(path => { delete pathmap[path]; });

      files.json.save(pathmapfile, pathmap);

        conf.nodes.json = conf.nodes.json.filter(addr => addr != relativeNodeFile);
        files.json.save(confile, conf);
