@contentful/field-editors

Playground with all components: http://contentful-field-editors.colorfuldemo.com/

This repository has all editorial components that you can find in the Contentful Web application. You can run each of these component as a custom field app or compose them into a custom entry app. You could also use these components as the basis for a custom Contentful App

• Single line editor
• Multi line editor
• Dropdown
• Tags
• List
• Checkbox
• Radio
• Boolean
• Rating
• Number
• Url
• JSON
• Location
• Date
• Markdown
• Slug
• Entry reference / Media
• Rich Text

Feel free to reach out to us with the ones that'd be the most useful to have here by filing a [Github issue][github-issues]!

Styles

To achieve the same field editor look as in the Contentful UI, you need to render GlobalStyled component.

import { GlobalStyles } from '@contentful/f36-components';
function Root() {
  return (
    <>
      <GlobalStyles />
      <MyApp />
    </>
  );
}

Linting

Ratchet approach

This repo uses a ratchet linter pattern. Each package/app has an eslint-suppressions.json file that records the count of known violations per file per rule. ESLint silences those existing violations so they don't block CI or development — but only up to the recorded count. Any new violation of the same rule in the same file still surfaces as an error.

The suppression files are a baseline that should only ever shrink. They must never be edited by hand or grown to hide a violation — adding a suppression is always a deliberate engineering decision, made via the commands below, never by manually editing the JSON.

Commands

Lint all packages (via [Lerna][lerna]'s --stream, one process per package):

yarn lint

Lint a single package (faster for local development):

cd packages/<name>
yarn lint

Pre-commit hook

On every commit, the pre-commit hook runs lint-staged inside each package via Lerna. It automatically removes stale suppressions (--prune-suppressions) for any file you changed. The updated eslint-suppressions.json is not included in the triggering commit — it appears as a modified file afterwards and must be committed separately (a post-commit hook reminds you of this).

Introducing a new lint rule

When a new ESLint rule triggers many existing violations across a package, use --suppress-all to baseline the current state before the rule becomes an error. Run this from inside the affected package:

cd packages/<name>
npx eslint src --suppress-all

This writes the current violations into that package's eslint-suppressions.json. Commit the updated suppression file together with the rule change. From that point on the ratchet applies: existing violations stay suppressed, all new code must comply.

Creating a canary release

Canary releases allow you to test changes before they are merged to the main branch.

Steps

1. Create a pull request targeting the canary branch (instead of master)
2. Once the PR is merged to canary, CircleCI will automatically:

1. You can install the canary version in your project:

yarn add @contentful/field-editor-reference@canaryversion

Notes

• Canary releases are temporary and intended for testing only
• Each merge to the canary branch will create a new canary version
• Canary versions follow the format: {version}-canary.{prNumber}.{shortSha}

Internationalization

The latest versions of field editors are internationalized with lingui. Any app using the latest field editors needs to include the @lingui/core and @lingui/message-utils packages and initialize lingui like this before rendering field editors:

import { i18n } from '@lingui/core';
import { compileMessage } from '@lingui/message-utils/compileMessage';
...
i18n.setMessagesCompiler(compileMessage);
i18n.activate('en-US');  // use desired locale code
const App = () => {
  ...
};
