# StringBatcher
A string processing batcher by chunks decomposition and handling!
Take string => process chunk by chunk!
Can be useful to all kind of things! One example would be to use with a notifier for a platform where messages are limited in size! For example telegram! By using the string batcher! You can create a notif method! That break down the long message! And send it by chunks automatically!
That just an example! It's a simple module for string batch processing!
## Construction
Constructor options:
```ts
export interface IOptions {
process: ProcessCallback,
batchSize: number
}
export type ProcessCallback = (str: string) => Promise<any>;
```
## Process string
```ts
public process(str: string): Promise<void>
```
To process a string we call the method above!
The method will be processed by chunk! Each time executing the processing callback!
## Example
```js
export function getStringBatchNotifier({
notifSysOptions,
stringBatcherOptions
}) {
const notificationSystem = new NotificationSystem(notifSysOptions);
const stringBatcher = new StringBatcher({
batchSize: stringBatcherOptions.batchSize || 4000,
process: async (chunk) => {
// One check processing
// in this example! Send a part of the message (telegram)
await notificationSystem.groupChat_sendTo({ message: chunk });
}
});
return async function notifier(message: string) {
await stringBatcher.process(message);
};
}
```
