ElectricSQL supports Node.js server applications using PGlite, our lightweight WebAssembly build of Postgres.


Add @electric-sql/pglite as a dependency to your app, e.g.:

npm install @electric-sql/pglite

See the PGlite repo for more information.


// Import the PGlite database client.
import { electrify } from 'electric-sql/pglite'

// Import the adapter to electrify PGlite from the ElectricSQL library.
import { PGlite } from '@electric-sql/pglite'

// Import your generated database schema.
import { schema } from './generated/client'

// Define custom configuration if needed
const config = {
url: ''

// Create the PGlite database connection. The first argument
// is your Postgres `pgdata` directory. Changing this will
// create/use a new local database.
const conn = new PGlite('/path/to/postgres/datadir')

// Instantiate your electric client.
const electric = await electrify(conn, schema, config)

// Connect to the sync service, passing along your authentication token
// See Usage -> Authentication for more details.
await electric.connect('your token')

You can now use the client to read, write and sync data, e.g.:

const { db } = electric

const results = await db.projects.findMany()

See Usage -> Data access and Integrations -> Frontend for more information.
