pgwait

Pauses execution of a Node.js application until a PostgreSQL connection becomes available.

Installing

npm i pgwait

Usage

import pgwait from 'pgwait'

await pgwait({
    host: 'localhost',      // PostgreSQL hostname or IP address.
    port: 5432,             // PostgreSQL port number.
    database: 'pgwait',     // PostgreSQL database. If omitted, PostgreSQL defaults to the username.
    user: 'postgres',       // PostgreSQL username.
    password: 'postgres',   // PostgreSQL password if the server requires authentication.
    retry: 2                // The retry interval in seconds.
})

Note: pgwait uses node-postgres under the hood. PostgreSQL environment variables will be used for undefined connection options.
