Build Process
This repository is setup as a monorepo with pnpm. The main components are in the apps and libs folders. They are linked together in one monorepo by pnpm, the file where this is specified is called pnpm-workspace.yaml. The apps folder contains the wallet-ui and wallet-api packages, the libs folder contains the dtos that are common between the wallet-ui and the wallet-api. At the root of the monorepo we define a root package.json and a Dockerfile. This means that there is one docker image for both the wallet-api and the wallet-ui. The wallet-ui can be enabled in the wallet-api by setting an environment variable called EMBEDDED_FRONTEND.
To make use of pnpm, make sure to install it. Then, to use the specific scripts in the root of the repository you can run:
pnpm install
And afterwards you can run a command by using pnpm ... with any command that is listed in the package.json file. If you want to run a command only for a specific package (for example wallet-api) you can run pmpm --filter wallet-api ... where at the dots you can place a command that is in the package.json of that specific app/lib.
Development
For development, everything is setup to be used with vscode. This means tests will automatically run on save, prettier will make code styling consistent, and debug scripts are available.
To run the wallet-ui and wallet-api in watch mode use the following command:
pnpm run dev:wallet-api
and
pnpm run dev:wallet-ui
Another option is to run them in parallel by running:
pnpm run dev --parallel
However, in that case you do not get the logs from both applications and some information might be missing from the logs.
If you want to test interactions between control planes excecute the following commands to generate a second instance. For this you would need to create a separate config file (based on the existing default config at ./apps/wallet-api/config.yaml) as well as provide the wallet-api used by the wallet-ui via the BACKEND environment variable:
CONFIG_PATH=$(pwd)/apps/wallet-api/config_second.yaml pnpm dev:wallet-api
BACKEND=http://localhost:3002 pnpm dev:wallet-ui
Docker
For building the docker image you can use the default docker commands to build and run the images and containers.
docker build -t control-plane .
Then run it:
docker run -p 3000:3000 control-plane
And visit http://localhost:3000 to view the control plane.
Database Schema Migrations
If changes are made to the data access objects (*.dao.ts) it is required to run the migrations scripts to ensure the database schemas can be applied / updated. The migration files are located under src/migrations with separate files for Postgres (*-postgres.ts) and SQLite (*-sqlite.ts).
Manual creation of migrations files is supported, but automated generation of migration files is supported by running (takes some time to run):
pnpm --filter wallet-api migrations:generate
In the CI pipelines automated checks are done in the testing stage to see whether migrations are required. You can manually execute this check to quickly see whether there is a need to generate new migrations:
pnpm --filter wallet-api migrations:check
Continuous Integration
The Continuous Integration pipelines will run every time a merge request is created. The CI pipeline consists of a few stages. Each stage will be described below.
Build
The first stage is to build the docker image. The type checks will be done and afterwards all the TypeScript files are transformed to javascript files to run in a docker container.
Dependency and container scanning
The dependencies and container is scanned for vulnerabilities. If there is a vulnerability, this needs to be fixed before merging the current merge request.
Tests
In the CI pipeline on Gitlab, the tests are automatically ran. They will also return a code coverage score. Please make sure this code coverage does not decrease too much when submitting Merge Requests.
Release
If all previous steps succeed, Semantic Versioning can be used to create a release including the new changes. It has been decided to not do this on every merge request, but on a manual click on a button by one of the administrators.
