forms-worker

This ia a monorepo for forms-worker/worker. A monorepo has been set up so it is easy to add new related services or code in future.

Prerequisites

  1. A node version manager, like nvm, or n
  2. node 20.x.x
  3. yarn >= v1.22. This project uses yarn 4. Yarn v1.22 will load the correct version of yarn by looking at .yarnrc and .yarn
  4. Docker >= 3.9 - Install docker engine

Install the dependencies by running yarn install from the root of the project.

@forms-queue/worker

Worker is a process which listens to a database-backed queue, and sends it to the configured webhook.

Use this component when you set XGovFormBuilder to use PGBOSS.

To start the project, you will need a running postgres database. You can start the database with docker by running the following command:

    docker compose up postgres

Or in detached mode (i.e. without tailing the logs)

    docker compose up postgres -d

This will start the postgres container running on port 5432; with username user and password root, and a database created called queue (postgres://user:root@localhost:5432/queue). init.sql is also loaded as a volume into the container, and will create a database named notarial (postgres://user:root@localhost:5432/notarial). This is useful if you are going to be running notarial-api at the same time. If you are running postgres from this repo, you do not need to run it in notarial-api.

Then to start the worker in dev mode,

    yarn worker start:local

Running with docker

You may use docker and docker compose to build and start the project with the right components (e.g. database, microservices), but will not be able to run the application(s) in dev mode (i.e. with watch and recompile).

To do this, simply run this command from the root of the project:

docker compose up -d

This will then run the server in a docker container in detached mode, allowing you to continue making commands through your terminal, but still keep the docker container running.

If you have already started a postgres container, you can comment out the postgres service in the docker-compose file.

To rebuild the server after making some changes, run the following commands:

docker compose down
docker compose -d --build

Formatting

This project uses ESLint and Prettier to ensure consistent formatting. It is recommended that you add and turn on the prettier plugin for your IDE, and reformat on save.

CI/CD

GitHub actions are being used to test, build, create releases and publish the docker images.

Release notes are auto-generated by semantic-release, based on semantic commit messages. The semantic version (semver) number will also be generated based on the merge message.

Prepend your commits or merge message with fix:, feat: , perf: or BREAKING CHANGE: to bump patch, minor, and major versions.

Troubleshooting

See TROUBLESHOOTING.md on how to troubleshoot the worker and errors when running the service.

Environment variables

Environment variable type Default Description
QUEUE_URL string postgres://user:root@localhost:5432/queue The connection string to the database, including username and password
ARCHIVE_FAILED_AFTER_DAYS string/int 30 How long to keep failed jobs in the pgboss.job before moving it to pgboss.archive
DELETE_ARCHIVED_IN_DAYS string/int 7 How long to keep jobs in pgboss.archive before deleting it
SUBMISSION_REQUEST_TIMEOUT string/int 2000 How long to keep the POST request alive for in milliseconds. This should be higher (20-30s) if integrating into CASEBOOK/Orbit which has long response times
NEW_JOB_CHECK_INTERVAL string/int 2000 The frequency to check for new jobs in milliseconds

Types are described as string/int since kubernetes only accepts strings. Strings are parsed into int.
