Giess den Kiez API based on Supabase

Supabase setup for Giess den Kiez

🚨 Might become part of the giessdenkiez-de repo eventually.

Prerequisites

• Supabase Account
• Supabase CLI install with brew brew install supabase/tap/supabase
• Docker Dependency for Supabase

Setup

Supabase (local)

git clone git@github.com:technologiestiftung/giessdenkiez-de-postgres-api.git
cd ./giessdenkiez-de-postgres-api
npm ci
# supabase needed for local development
supabase login
# Check if docker is running
docker --version
# then run
supabase start
# After a few minutes you will have a local supabase instance running with
# - Postgres DB at postgrsql://postgres:postgres@localhost:5432/postgres
# - Postgrest API at http://localhost:54321 a rest api for your db
# - Supabase Studio at http://localhost:54323 a gui for your db
# - Other cool things we currently don't use
# The Database will already have some seeded trees in Berlin

# Create .env file and populate with ENV variables from the supabase start command
#  You can always get the values again by running `supabase status`
cp .env.example .env
# SERVICE_ROLE_KEY=...
# SUPABASE_URL=...
# SUPABASE_ANON_KEY=...
# SUPABASE_MAX_ROWS=1000

Environments and Variables

In the example code above the Postgres database Postgrest API are run locally. You SHOULD NOT use production variables in your local or CI environments. The tests will modify the database and also truncate tables through the API and also with direct calls.

Again. Be a smart developer, read https://12factor.net/config, https://github.com/motdotla/dotenv#should-i-have-multiple-env-files and never ever touch production with your local code!

Supabase

You can sign up with the request below. You will get an access token to use in your requests.

curl --request POST \
  --url http://localhost:54321/auth/v1/signup \
  --header 'apikey: <SUPABASE ANON KEY>' \
  --header 'content-type: application/json' \
  --header 'user-agent: vscode-restclient' \
  --data '{"email": "someone@email.com","password": "1234567890"}'

curl --request POST \
  --url http://localhost:8080/post/adopt \
  --header 'authorization: Bearer <ACCESS_TOKEN>' \
  --header 'content-type: application/json' \
  --data '{"tree_id":"_01","uuid": "<YOUR USERS ID>"}'

The user id will be removed in future versions since the supabase SDK can get the user id from the access token and each token is bound to a specific user.

Tests

Locally you will need supabase running and a .env file with the right values in it.

cd giessdenkiez-de-postgres-api
supabase start
# Once the backaned is up and running, run the tests
# Make sure to you habe your .env file setup right
# with all the values from `supabase status`
npm test

On CI the Supabase is started automagically. See .github/workflows/tests.yml

To run the tests for the Supabase Edge Functions, execute locally:

cd giessdenkiez-de-postgres-api
docker run -p 1025:1025 mailhog/mailhog
supabase start
supabase functions serve --no-verify-jwt --env-file supabase/.env.test
deno test --allow-all supabase/functions/tests/submit-contact-request-tests.ts --env=supabase/.env.test

Supabase

Migrations and Types

• Run supabase start to start the supabase stack
• make changes to your db using sql and run supabase db diff --file <MIGRATION FILE NAME> --schema public --use-migra to create migrations
• Run supabase gen types typescript --local > ./_types/database.ts to generate typescript types for your DB.

Deployment

• Create a project on supabase.com
• Configure your GitHub actions to deploy all migrations to staging and production. See .github/workflows/deploy-to-supabase-staging.yml and .github/workflows/deploy-to-supabase-production.yml for an example. We are using actions environments to deploy to different environments. You can read more about it here: https://docs.github.com/en/actions/reference/environments.
  • Needed variables are:
    • DB_PASSWORD
    • PROJECT_ID
    • SUPABASE_ACCESS_TOKEN
• (Not recommended but possible) Link your local project directly to the remote supabase link --project-ref <YOUR PROJECT REF> (will ask you for your database password from the creation process)
• (Not recommended but possible) Push your local state directly to your remote project supabase db push (will ask you for your database password from the creation process)

Supabase Auth

Some of the requests need a authorized user. You can create a new user using email password via the Supabase API.

curl --request POST \
  --url http://localhost:54321/auth/v1/signup \
  --header 'apikey: <SUPABASE_ANON_KEY>' \
  --header 'content-type: application/json' \
  --data '{"email": "someone@email.com","password": "1234567890"}'

This will give you in development already an aceess token. In production you will need to confirm your email address first.

A login can be done like this:

curl --request POST \
  --url 'http://localhost:54321/auth/v1/token?grant_type=password' \
  --header 'apikey: <SUPABASE_ANON_KEY>' \
  --header 'content-type: application/json' \
  --data '{"email": "someone@email.com","password": "1234567890"}'

See the docs/api.http file for more examples or take a look into the API documentation in your local supabase instance under http://localhost:54323/project/default/api?page=users

Supabase Edge Functions

To run the Supabase Edge Functions locally:

• Setup the .env file in supabase/.env according to supabase/.env.sample
• Note: The env variables SUPABASE_SERVICE_ROLE_KEY and SUPABASE_URL are injected automatically and can't be set the in the supabase/.env file. If you want to overwrite them, you have to rename the environment variables to not start with SUPABASE_. For reference, see: https://supabase.com/docs/guides/functions/secrets
• With the environment variables setup correctly, execute supabase functions serve --no-verify-jwt --env-file supabase/.env

To deploy the Edge Functions in your linked remote Supabase project, execute:

• supabase functions deploy
• Make sure that you set the proper environment variables in the remote Supabase project too

Tests

Locally you will need supabase running and a .env file with the right values in it.

cd giessdenkiez-de-postgres-api
supabase start
# Once the backaned is up and running, run the tests
# Make sure to you habe your .env file setup right
# with all the values from `supabase status`
npm test

On CI the Supabase is started automagically. See .github/workflows/tests.yml
