Install the required python packages

pip install -r requirements.txt

A separate environment is provided for developers

pip install -r dev_requirements.txt

The *requirements.txt files are generated using pip-tools. See REQUIREMENTS.md for instructions on using pip-tools and upgrading packages in Troposphere.

The webpack-dev-server will serve new bundles to a browser when files change.

It has the following features:

• Changes result in a browser refresh (you know they are propagated)
• The bundle is served from memory not disk
• Small changes result in small compiles

Currently troposphere uses nginx to serve its assets. This makes it trivial to serve these assets from the dev server.

Update your nginx definition (at /etc/nginx/locations/tropo.conf)

location /assets {
    # This just needs to point to the dev server which runs on 8080
    proxy_pass https://server.example.com:8080;
}

Finally start the dev server:

npm run serve -- --host server.example.com --port 8080 --https  --cert /path/to/cert --key /path/to/key

If you would like to enable CSS hot reloading, prefix the npm command like so:

CSS_IN_JS=true npm run serve ...

By default we extract CSS from the larger bundle into a separate asset that is parsed/loaded before any js, this ensures that the content of our html will be styled the first time it is shown. However, CSS hot reloading only works if the CSS is shipped in the JS. The caveat is that html content is shipped without initial styling.

Note: CSS_IN_JS is completely ignored in a production environment.
