unleash-server

unleash-server is a place to ask for the status of features.

Create a local unleash-db on postgres

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

Then set up your DATABASE_URI env.var:

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

Important commands:

// Install dependencies
npm install

// Make sure DATABASE_URL is set and run migrations in your local DB
./node_modules/.bin/db-migrate up

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

// Admin dashboard
http://localhost:4242

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

// Execute tests:
npm 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 npm run db-migrate-up.
5. Generate LB artifact using scripts/generate-liquibase-artifact (TODO: make this internal)
