Requirements

Node.js

Please install Node.js >= v22 and npm >= v11. You will find it easier to use the Node Version Manager nvm

To use the correct version of Node.js for this application, via nvm:

cd fcp-dal-api
nvm use

Local development

Setup

Install application dependencies:

npm install

Development

To run the application in development mode run:

npm run dev

Testing

To test the application run:

npm run test

Production

To mimic the application running in production mode locally run:

npm start

Npm scripts

All available Npm scripts can be seen in package.json. To view them in your command line run:

Update dependencies

To update dependencies use npm-check-updates:

The following script is a good start. Check out all the options on the npm-check-updates

ncu --interactive --format group

Formatting

Windows prettier issue

If you are having issues with formatting of line breaks on Windows update your global git config by running:

git config --global core.autocrlf false

API endpoints

Endpoint	Description
GET: /health	Health

Security

The platform provides features for handling authentication to the DAL, connecting clients can follow the CDP docs.

NOTE: the endpoint protection can be changed by submitting a PR with changes to this spec file

Development helpers

Proxy

We are using forward-proxy which is set up by default. To make use of this: import { fetch } from 'undici' then because of the setGlobalDispatcher(new ProxyAgent(proxyUrl)) calls will use the ProxyAgent Dispatcher

If you are not using Wreck, Axios or Undici or a similar http that uses Request. Then you may have to provide the proxy dispatcher:

To add the dispatcher to your own client:

import { ProxyAgent } from 'undici'

return await fetch(url, {
  dispatcher: new ProxyAgent({
    uri: proxyUrl,
    keepAliveTimeout: 10,
    keepAliveMaxTimeout: 10
  })
})

Docker
