Installation

npm install provide-id-gen --save

Usage

Pass any set of keys (an array of strings) to the provideIdGen function and it will return a provider with genId action(s) and newId reducer(s) based on each key. Each key is usually some provider key for which you would like to generate IDs.

Example

// src/providers/idGen.js
 
import provideIdGen from 'provide-id-gen';
 
const idGen = provideIdGen([
  'foo',
  'bar'
]);
 
export default idGen;

You'll then have a provider with the following actions:

• genFooId - Increments and returns the current fooId.
• genBarId - Increments and returns the current barId.

And reducers:

• newFooId - The current new fooId.
• newBarId - The current new barId.

Protip

On the server, you should probably set isGlobal to true. This will ensure the same provider instance is used across multiple requests and prevent any race conditions with replication if/when some ID of the same key is generated for more than one request at almost the exact same time.
