Getting Started

Install using any of these package manager.s

npm install @codeium/react-code-editor

# Yarn
yarn add @codeium/react-code-editor

pnpm install @codeium/react-code-editor

Now import the CodeiumEditor and enjoy lightning fast AI autocomplete, directly in your browser, 100% for free!

import { CodeiumEditor } from "@codeium/react-code-editor";

export const IdeWithAutocomplete = () => {
  return (
      <p>Here's an AI-powered Python editor using Codeium.</p>
      <CodeiumEditor language="python" theme="vs-dark" />

Here's an advanced example that uses multi-document context to provide more intelligent autocompletion:

import { CodeiumEditor, Document, Language } from "@codeium/react-code-editor";

export const JavaScriptEditorWithContext = () => {
  const html = `<html>
    <h1>Contact Us</h1>
      <input id="name" type="text" />
      <input id="email" type="text" />

  return (
      <p>This editor has context awareness of a neighboring HTML file and can provide better autocompletion suggestions.</p>
          new Document({
            absolutePath: "/app/index.html",
            relativePath: "index.html",
            text: html,
            editorLanguage: "html",
            language: Language.HTML,

Note that the otherDocuments prop has a limit of 10 documents. Within those documents, Codeium will run a reranker behind the scenes to optimize what is included in the token limit.


Here are some examples of Codeium React Editor used in production:

How it works

This project is a wrapper around Microsoft's Monaco editor which is the editor that powers VS Code with the extended capability of providing code autocompletion.

The autocompletes are provided by analyzing the editor's content and predicting and providing suggestions based on that context. To learn more about how the autocompletion works, visit Codeium's FAQ.

What is Codeium

Codeium is a free, AI-powered developer toolkit that plugs into 70+ IDEs, including: Visual Studio Code, JetBrains IDEs, Google Colab, and Vim. Codeium provides unlimited AI context-aware autocomplete, chat assistant, intelligent search, codebase indexing, and more. Codeium also offers flexible deployments within your VPC or in on-prem, airgapped environments. Learn more at codeium.com.


The core API of the editor is the same as that of the wrapped project. You can view the editor API here.


How can I import the ESM version of this?

To import the ESM version of this, you can use import { CodeiumEditor } from "@codeium/react-code-editor/dist/esm";. If you're using TypeScript, your editor might warn that the types are missing. A current workaround is:

  • Create a codeiumeditor.d.ts file,
  • Add declare module '@codeium/react-code-editor/dist/esm'; to the file
  • Import the types file in the file using the CodeiumEditor component.

This is an open issue in terms of supporting both CommonJS and ESM. If you're interested in contributing and have a fix for this, pull requests are welcome.


This project would not have been possible without Suren Atoyan's Monaco React project.
