Enterprise ready feature toggles service

unleash

Demo instance on Heroku

This repo contains the unleash-server, which contains the admin UI and a place to ask for the status of features. In order to make use of unleash you will also need a client implementation.

Known client implementations:

• unleash-client-java
• unleash-client-node

Development

Create a local unleash databases in postgres

$ psql postgres <<SQL
CREATE USER unleash_user WITH PASSWORD 'passord';
CREATE DATABASE unleash;
GRANT ALL PRIVILEGES ON DATABASE unleash to unleash_user;
CREATE DATABASE unleash_test;
GRANT ALL PRIVILEGES ON DATABASE unleash_test to unleash_user;
SQL

Then set env vars:

export DATABASE_URL=postgres://unleash_user:passord@localhost:5432/unleash
export TEST_DATABASE_URL=postgres://unleash_user:passord@localhost:5432/unleash_test

Commands

// Install dependencies
npm install

// Run migrations in your local DBs
./node_modules/.bin/db-migrate up
DATABASE_URL=$TEST_DATABASE_URL ./node_modules/.bin/db-migrate up

// Start server in dev-mode:
npm run dev

// Admin dashboard
http://localhost:4242

// Feature API:
http://localhost:4242/features

// Execute tests:
npm test

// Run tests with postgres running in docker:
npm run docker-test

Making a schema change

1. Create migrations/sql/NNN-your-migration-name.up.sql with your change in SQL.
2. Create migrations/sql/NNN-your-migration-name.down.sql with the rollback of your change in SQL.
3. Run db-migrate create your-migration-name and edit the generated file to have this line: module.exports = require('../lib/migrationRunner').create('NNN-your-migration-name');
4. Run db-migrate up.
5. Generate LB artifact using scripts/generate-liquibase-artifact (TODO: make this internal)
