studio-frontend

React front end for edX Studio

Development

Requirements:

• Docker 17.06 CE+, which should come with docker-compose built in.
• A working, running edX devstack

To install and run locally:

$ git clone [e-mail]:edx/studio-frontend.git
$ cd studio-frontend
$ make up

You can append -detached to the make up command to run Docker in the background.

To install a new node package in the repo (assumes container is running):

$ make shell
$ npm install <package> --save-dev
$ exit
$ git add package.json

To make changes to the Docker image locally, modify the Dockerfile as needed and run:

$ docker build -t edxops/studio-frontend:latest .

Webpack will serve pages in development mode at http://localhost:18011.

The following pages are served in the development:

Page	URL
Assets	http://localhost:18011/assets.html
Accessibility Policy	http://localhost:18011/accessibilityPolicy.html
Edit Image Modal	http://localhost:18011/editImageModal.html

Notes:

The development server will run regardless of whether devstack is running along side it. If devstack is not running, requests to the studio API will fail. You can start up the devstack at any time by following the instructions in the devstack repository, and the development server will then be able to communicate with the studio container. API requests will return the following statuses, given your current setup:

Studio Running?	Logged in?	API return
No	n/a	504
Yes	No	404
Yes	Yes, non-staff account	403
Yes	Yes, staff account	200

Development Inside Devstack Studio

To load studio-frontend components from the webpack-dev-server inside your studio instance running in Devstack:

1. In your devstack edx-platform folder, create cms/envs/private.py if it does not exist already.
2. Add STUDIO_FRONTEND_CONTAINER_URL = 'http://localhost:18011' to cms/envs/private.py.
3. Reload your Studio server: make studio-restart.

Pages in Studio that have studio-frontend components should now request assets from your studio-frontend docker container's webpack-dev-server. If you make a change to a file that webpack is watching, the Studio page should hot-reload or auto-reload to reflect the changes.

Testing the Production Build Inside Devstack Studio

The Webpack development build of studio-frontend is optimized for speeding up developement, but sometimes it is necessary to make sure that the production build works just like the development build. This is especially important when making changes to the Webpack configs.

Sandboxes use the production webpack build (see section below), but they also take a long time to provision. You can more quickly test the production build in your local docker devstack by following these steps:

1. If you have a cms/envs/private.py file in your devstack edx-platform folder, then make sure the line STUDIO_FRONTEND_CONTAINER_URL = 'http://localhost:18011' is commented out.
2. Reload your Studio server: make studio-restart.
3. Run the production build of studio-frontend by running make shell and then npm run build inside the docker container.
4. Copy the production files over to your devstack Studio's static assets folder by running this make command on your host machine in the studio-frontend folder: make copy-dist.
5. Run Studio's static asset pipeline: make studio-static.

Your devstack Studio should now be using the production studio-frontend files built by your local checkout.

Testing a Branch on a Sandbox

It is a good practice to test out any major changes to studio-frontend in a sandbox since it is much closer to a production environment than devstack. Once you have a branch of studio-frontend up for review:

1. Create a new branch in edx-platform off master.

2. Edit the package.json in that branch so that it will install studio-frontend from your branch in review:

   "@edx/studio-frontend": "edx/studio-frontend#your-branch-name",
   

3. Commit the change and push your edx-platform branch.

4. Follow this document on provisioning a sandbox using your edx-platform branch.

The sandbox should automatically pull the studio-frontend branch, run the production webpack build, and then install the dist files into its static assets during provisioning.

Releases

This all happens automagically on merges to master, hooray! There are just a few things to keep in mind:

What is the latest version?

Check github, npm, or the npm badge at the top of this README. package.json no longer contains the correct version (on Github), as it creates an odd loop of "something merged to master, run semantic-release" -> "semantic-release modified package.json, better check that in and make a PR" -> "a PR merged to master, run semantic-release", etc. This is the default behavior for semantic-release.

Commit message linting

In order for semantic-release to determine which release type (major/minor/patch) to make, commits must be formatted as specified by these Angular conventions. TravisBuddy will let you know if anything is wrong before you merge your PR. It can be difficult at first, but eventually you get used to it and the added value of automatic releases is well worth it, in our opinions.

A note on merge messages

Note that when you merge a PR to master (using a merge commit; we've disabled squash-n-merge), there are actually 2 commits that land on the master branch. The first is the one contained in your PR, which has been linted already. The other is the merge commit, which commitlint is smart enough to ignore due to these regexes. The point here is that you should not change the default Merge pull request <number> from <branch> message on your merge commit, or else the master build will fail and we won't get a deploy.

Updating Latest Docker Image in Docker Hub

If you are making changes to the Dockerfile or docker-compose.yml you may want to include them in the default docker container.

1. Run make from-scratch
2. Run docker tag edxops/studio-frontend:latest edxops/studio-frontend:latest
3. Run docker push edxops/studio-frontend:latest
4. Check that "Last Updated" was updated here: https://hub.docker.com/r/edxops/studio-frontend/tags/
