What it is

Formik is a React form state management library that abstracts away the complexity of form handling—validation, error messages, touched fields, submission—into a simple, declarative API. It eliminates boilerplate for common form patterns and integrates seamlessly with Yup for schema validation. Monorepo using Yarn workspaces: packages/formik/ contains the core React library (Formik.tsx, Field.tsx, FieldArray.tsx, Form.tsx components and utils); packages/formik-native/ provides React Native support; app/ is a Next.js demo application showcasing form examples. TypeScript as primary language with .changeset/ for release coordination.

Start here

Open these first:

• packages/formik/src/Formik.tsx — Core Formik component that manages form state, validation, and submission logic—the primary entry point for form management.
• packages/formik/src/FormikContext.tsx — React Context provider that makes form state available to nested components throughout the form tree.
• packages/formik/src/Field.tsx — Field component that connects individual input elements to Formik state and handles value binding, errors, and touched state.
• packages/formik/src/types.tsx — TypeScript type definitions for all public APIs, validation schemas, and form state interfaces used across the library.
• packages/formik/src/index.tsx — Main library export barrel file that defines the public API surface and re-exports all user-facing components and hooks.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/jaredpalmer/formik.git
cd formik
yarn install
cd app
yarn dev

This clones the repo, installs workspace dependencies via Yarn (inferred from yarn.lock), navigates to the example app, and starts the Next.js dev server on http://localhost:3000.

Daily commands:

cd app
yarn dev

Starts the Next.js development server. See app/package.json: dev script runs 'next dev'. For production: 'yarn build' then 'yarn start'.

Key cautions & unknowns

• Slowing — last commit 10mo ago
• Scorecard: marked unmaintained (0/10)
• No required environment variables evident, but verify before running: Next.js demo (app/) expects Node.js compatible with ^12.0.0. TypeScript strict mode enabled in tsconfig files—type mismatches will block builds.…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
