Remove Legacy Web IDE frontend
Issue: Remove legacy Web IDE frontend source code (#537160 - closed)
What does this MR do and why?
It removes the source code of the legacy Web IDE that isn't used by other features in the GitLab application. For example:
- It removes Vue components and Vuex store implementations.
- It removes CSS stylesheets.
- It removes custom ESLint configuration and rule violations exceptions.
NOTICE This Merge Request doesn't remove any code in app/assets/javascripts/ide that is used by other modules in app/assets/javascripts. For example, we noticed that the modules app/assets/javascripts/editor and app/assets/javascripts/diffs depend on some utilities defined in the legacy Web IDE. This MR doesn't attempt to refactor these dependencies with the goal of keeping its scope under control. We will defer this refactoring to follow-up Merge Requests.
We removed the entry point to the Legacy Web IDE and the feature flag that controlled access its access !188427 (merged). This Merge Request doesn't have user-facing consequences because the code removed is not referenced by any production feature.
