## PostgreSQL
|
|
To run and develop unleash you need to have PostgreSQL databse (PostgreSQL v.9.5.x or newer) locally.
|
|
|
|
|
|
### Create a local unleash databases in postgres
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
(Optional as unleash will asume these as default values).
|
|
|
|
```
|
|
export DATABASE_URL=postgres://unleash_user:passord@localhost:5432/unleash
|
|
export TEST_DATABASE_URL=postgres://unleash_user:passord@localhost:5432/unleash_test
|
|
```
|
|
|
|
## PostgreSQL with docker
|
|
If you dont want to install PostgreSQL locally you can spin up an instance with docker.
|
|
We have created a script to ease this process: `scripts/docker-postgres.sh`
|
|
|
|
|
|
## Commands
|
|
|
|
```
|
|
// Install dependencies
|
|
npm install
|
|
|
|
// Build unleash-frontend
|
|
// (yes this is a bit wierd and be easier when we have a release of the frontend artifact).
|
|
// You can of course "npm link unleash-frontend" instead
|
|
cd node_modules/unleash-frontend && npm install
|
|
|
|
// Start server in development
|
|
npm start:dev
|
|
|
|
// Admin dashboard
|
|
http://localhost:4242
|
|
|
|
// Feature API:
|
|
http://localhost:4242/api/features
|
|
|
|
// Execute tests in all packages:
|
|
npm test
|
|
```
|
|
|
|
## Database changes
|
|
|
|
We use database migrations to track database changes.
|
|
|
|
### 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('../scripts/migration-runner').create('NNN-your-migration-name');`
|
|
4. Run `db-migrate up`.
|
|
|
|
|
|
## Publishing / Releasing new packages
|
|
|
|
Please run `npm run nsp` nad `npm run lint` checks before publishing.
|
|
|
|
Run `npm run publish` to start the publishing process.
|
|
Lerna is setup with independent versioning so you will be prompted with version per package, and lerna will update all the versions across packages.
|
|
|
|
`npm run publish:dry` |
