Formik Fork README

This is a Fork of the original Formik repository. It is intended to be used as a dependency in other projects with minimal changes to address bugs, since the original repository is not actively maintained (as of March 2025).

The main branch contains the original Formik codebase, while the main-dev branch is the main development branch for this fork.

This Fork has a custom-publish script.

yarn custom-publish

This should be called from the main-dev branch after making/merging changes to the codebase. The script builds the package and updates a dedicated custom-build branch containing only the distributable files. It then commits and force‑pushes these changes to GitHub, allowing you to continuously install the latest build with:

yarn add git+https://github.com/zduvall/formik.git#custom-build

Note that the custom-publish script uses a custom script, also named custom-build, which forces a build even if there are no detected changes.

This monorepo uses yarn, so to start you'll need the package manager installed.

To run E2E tests you'll also need Playwright set up, which can be done locally via npx playwright install. Afterward, run yarn start:app and in a separate tab run yarn e2e:ui to boot up the test runner.

When you're done with your changes, we use changesets to manage release notes. Run yarn changeset to autogenerate notes to be appended to your pull request.

Thank you!
