FRA Platform

Prerequisites

First, install Yarn (modern npm replacement).

Then, install NodeJs (currently the LTS version we are using is 20.11.1).

The .env file

The .env file is needed for development and locally running the stack.

It must be added to the root directory of the project and match the .env.template

Building web application

To build it once:

yarn run build

To constantly build it when something changes, run:

yarn watch

Running the server

yarn start

* Backend Storage Setup

Postgres

Create a new Postgres local instance via Docker. Run the command:

sudo docker run -d --name fra-db -p 5442:5432 -e POSTGRES_DB=frap-dev -e POSTGRES_PASSWORD=frap -e POSTGRES_USER=frap postgres:15.4

Otherwise, check .env configurations for setting it up manually (note that the server port is not default!)

Redis

Install 2 instances of redis 6.2.6 (one for queues and one for data)

sudo docker run --name fra-queue-redis -p 6379:6379 -d redis:6.2.6

sudo docker run --name fra-data-redis -p 6389:6379 -d redis:6.2.6

Database Migrations

Migrations are run automatically on startup of the server.

Adding a database migration

When you need e.g. a new table to the database (say "kuikka"), create a migration template with:

yarn migration-public:create kuikka

Now you'll see new sql files in src/tools/migrations/public/steps/.

You should edit the <timestamp-kuikka-up.ts to contain your create table -statement. Make sure migrations can be ran twice without side effects.
