The Front End¶
Pegasus’s front-end architecture is a hybrid model, with a standalone front-end codebase that is compiled and served inside Django templates.
Pegasus’s styles use either the Bootstrap or Bulma CSS frameworks, and building the CSS files is included as part of the front-end build pipeline. For more details on CSS in Pegasus, see the CSS documentation.
The source front-end files live in the
assets directory, while the compiled files
get created in the
Generally you should only ever edit the front-end files in
and compile them using the instructions below.
Prerequisites to building the front end¶
Getting started should be as simple as running:
In your project’s root directory. This will install all the dependencies necessary to build the front end.
It will also generate a
It is recommended that you add this file to source control for consistency across installations.
Building in Development¶
Whenever you make modifications to the front-end files you will need to run the following command to rebuild the compiled JS bundles and CSS files:
npm run dev
You can also set it up to watch for changes by running:
npm run dev-watch
Building for production¶
To build for production, run:
npm run build
This will compress your files, remove logging statements, etc.
Deployment best practices¶
For ease of initial set up, the front-end bundle files are included with the Pegasus codebase. This allows you to get up and running with Pegasus without having to set up the front-end build pipeline.
However, after you have set up the front-end toolchain it is recommended that you:
- Add the bundle files to your .gitignore so they are no longer managed by source control.
- Build the bundle files on your production server (using
npm install && npm run build) as part of your CI/CD deployment process.
This will ensure that the latest, optimized version of the front-end code is always deployed as part of your production environment.
