Knex Env Config

Create Knex config objects with defaults loaded from the environment.

Usage

Install

npm install knex-env-config

Example

Create a Knex config object by calling knexEnvConfig and pass it to the Knex constructor:

import Knex from 'knex';
import knexEnvConfig from 'knex-env-config';

const knexConfig = knexEnvConfig();
const knex = Knex(knexConfig);

Or override some options:

const knexConfig = knexEnvConfig({
  client: 'sqlite3',
  connection: {
    filename: 'database.sqlite',
  },
});

const knex = Knex(knexConfig);

Or pass a custom env object:

const env = {
  DATABASE_USER: 'root'
};
const knexConfig = knexEnvConfig.withEnv({
  client: 'pg',
  connection: {
    host: 'localhost',
  },
}, env);

const knex = Knex(knexConfig);
