Digital Marketplace User Frontend

Frontend application for the Digital Marketplace.

• Python app, based on the Flask framework

This app contains:

• user logins
• password management
• setting cookie preferences

Quickstart

It's recommended to use the DM Runner tool, which will install and run the app as part of the full suite of apps.

If you want to run the app as a stand-alone process, clone the repo then run:

make run-all

This command will install dependencies and start the app.

By default, the app will be served at http://127.0.0.1:5007/user.

API dependencies

(If you are using DM Runner you can skip this section.)

The User Frontend app requires access to the API app. The location and access token for this service are set with environment variables in config.py.

For development, you can either point the environment variables to use the preview environment's API box, or use a local API instance if you have one running:

export DM_DATA_API_URL=http://localhost:5000
export DM_DATA_API_AUTH_TOKEN=<auth_token_accepted_by_api>

Where DM_DATA_API_AUTH_TOKEN is a token accepted by the Data API instance pointed to by DM_API_URL.

Testing

Run the full test suite:

make test

To only run the Python or Javascript tests:

make test-python
make test-javascript

To run the flake8 linter:

make test-flake8

Updating Python dependencies

requirements.txt file is generated from the requirements.in in order to pin versions of all nested dependencies. If requirements.in has been changed (or we want to update the unpinned nested dependencies) requirements.txt should be regenerated with

make freeze-requirements

requirements.txt should be committed alongside requirements.in changes.

Frontend assets

Front-end code (both development and production) is compiled using Node and Gulp.

Requirements

You need Node (try to install the version we use in production - see the base docker image).

To check the version you're running, type:

node --version

Frontend tasks

npm is used for all frontend build tasks. The commands available are:

• npm run frontend-build:development (compile the frontend files for development)
• npm run frontend-build:production (compile the frontend files for production)
• npm run frontend-build:watch (watch all frontend+framework files & rebuild when anything changes)

Updating NPM dependencies

Update the relevant version numbers in package.json, then run

npm install

Commit the changes to package.json and package-lock.json.

You can also run npm audit fix to make minor updates to package-lock.json.
