@pryv/datastore v1.0.0

Pryv.io data store

Library and tools for accessing external data stores within Pryv.io.

⚠️ This is the first public release; the following are still likely to change:

• Code examples
• API documentation
• (For contributors) Development environment

Quick start

To let Pryv.io access an external data store:

Create your data store implementation in Node.js based on the present library

1. npm install --save @pryv/datastore

2. Implement a data store in your package's main module; for example:

   const ds = require('@pryv/datastore');
   
   module.exports = ds.createDataStore({
     async init (params) {
       this.settings = params.settings;
   
       // initialization code goes here…
   
       // if implementing streams
       this.streams = ds.createUserStreams({
         // streams store implementation here…
       });
   
       // if implementing events
       this.events = ds.createUserEvents({
         // events store implementation here…
       });
   
       return this;
     },
   
     async deleteUser (userId) {
       // remove user from store…
     },
   
     async getUserStorageSize (userId) {
       // compute user storage bytes…
     }
   })

For the details, see the API documentation.

Install it on your Pryv.io core machines

1. Deploy your module in your chosen location on each core machine
2. Register it in platform configuration under key custom:dataStores; each data store definition has those properties:
   • id (string): The store's id – this is used in data so do not change
   • name (string): The store's name, for logging and messaging purposes
   • settings (object): Any settings to pass to your data store implementation
