So, I tested this on a lot of sites (cf list at the top) and it seems to work great in most cases, just noted a few minor changes to do. We'll likely do one last Webpack 4 bugfix release soon and then merge this PR next week. |

Glad to receive your PR! @slorber And if it's ready to merge, just let us know :) |

Summary: Use an unreleased version of Docusaurus to test the webpack5 support works for this site, detect potential problems, and perf improvements. See also facebook/docusaurus#4089 Perf improvements - First build (local): 300s - Second build (local): 90s To get the benefits, it requires caching `node_modules/.cache`. It is not possible in GH actions, so I suggest migrating the site to Netlify and use the appropriate toml config (example: https://github.com/react-navigation/react-navigation.github.io/pull/974/files) --- Unrelated suggestion: Relay has a lot of versions and long build/start times Assuming nobody ever edit Relay docs of 2 years ago, you can improve the DX by limiting the number of versions display in dev with this docs plugin config: ``` onlyIncludeVersions: (isDev || isDeployPreview) ? ['current', ...versions.slice(0, 2)] : undefined, ``` For faster prod build, you can also move older docs to standalone deployments and link to them (see Jest for versions < 25 => https://jestjs.io/) Pull Request resolved: #3469 Reviewed By: rbalicki2 Differential Revision: D28127629 Pulled By: jstejada fbshipit-source-id: c78309aa1c7f14f22ecc33166ad5dce7d2e51f94

Issue: #4027
Released in 2.0.0-alpha.75
Breaking changes
As it's a major Webpack version upgrade, it is a breaking change and can require adapt things on your sites such as the
configureWebpackof your custom plugins.However, sites that do not have custom plugins and mostly use a basic config should be able to upgrade seamlessly.
Please report any issues otherwise.
Known issues:
Using persistent caching
Make your CI cache the
node_modules/.cachefolder across 2 CI builds, and the 2nd build becomes much faster.If you get some deprecation warnings, please report them here with the stacktrace, by running
NODE_OPTIONS='--trace-warnings' yarn buildTested on a lot of sites with great success:
