Official libraries

Filecheck ships five official libraries. The browser packages are thin, typed wrappers around the Element — the Element itself always loads from the Filecheck CDN, so UI updates reach you without a package upgrade. The server packages wrap the REST API with typed clients, retries, and a one-call job verification helper.

Package	Registry	Use it for
`filecheck-js`	npm	Typed loader for the Element + all shared TypeScript types
`filecheck-react`	npm	React component and hooks wrapping the Element
`filecheck-vue`	npm	Vue 3 component and composable wrapping the Element
`filecheck-node`	npm	Node.js server SDK — jobs, uploads, webhooks, `jobs.verify()`
`filecheck/filecheck-php`	Packagist	PHP server SDK, mirroring the Node.js SDK

Install

npm install filecheck-js
# with a framework wrapper:
npm install filecheck-react filecheck-js
npm install filecheck-vue filecheck-js

npm install filecheck-node

composer require filecheck/filecheck-php

Which do I need?

A complete integration has two halves, and you typically pick one package from each:

Client — embed the Element so customers upload, see findings, and get auto-fixes. Use filecheck-js on vanilla stacks, or filecheck-react / filecheck-vue inside those frameworks. Gate your submit button on canProceed and carry the jobId to your server.
Server — before fulfilling, verify the submitted jobId with your secret key. Use filecheck-node or filecheck/filecheck-php; both encode the verification checklist in a single verify() call.

Not on npm or Composer? The plain <script> embed works everywhere — see Element on a custom stack. No browser in the flow at all? Use the headless API integration.

All packages are MIT licensed and developed in the open at github.com/PrintApp/filecheck-integrations (PHP: github.com/PrintApp/filecheck-php).
