Workers

Create an Artifacts repo from a Worker and use a standard Git client to push and pull content.

By the end of this guide, you will create a Worker, bind it to Artifacts, create a repo through the Workers binding, push a commit, and clone the same repo back with a standard Git client.

Start by reading Namespaces, then choose the namespace name you will use. This guide uses default in the examples.

Prerequisites

  1. Sign up for a Cloudflare account ↗.
  2. Install Node.js ↗.

Node.js version manager

Use a Node version manager like Volta ↗ or nvm ↗ to avoid permission issues and change Node.js versions. Wrangler, discussed later in this guide, requires a Node version of 16.17.0 or later.

You also need:

  • Wrangler installed. If you use local Wrangler commands in this guide, authenticate Wrangler first. For local OAuth authentication or CI setup, refer to wrangler login and Running Wrangler in CI/CD.
  • Access to Artifacts in your Cloudflare account.
  • A namespace name, for example default.
  • A local git client.
  • jq, if you want to extract response fields automatically.

1. Create a Worker project

  1. Create a new Worker project with C3:

    npm create cloudflare@latest -- artifacts-worker

    For setup, select the following options:

    • For What would you like to start with?, choose Hello World example.
    • For Which template would you like to use?, choose Worker only.
    • For Which language do you want to use?, choose TypeScript.
    • For Do you want to use git for version control?, choose Yes.
    • For Do you want to deploy your application?, choose No (we will be making some changes before deploying).

  2. Move into the project directory:

    Terminal window
    cd artifacts-worker

2. Add the Artifacts binding

Open your Wrangler config file and add the Artifacts binding:

JSONC
{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "name": "artifacts-worker",
  "main": "src/index.ts",
  // Set this to today's date
  "compatibility_date": "2026-05-23",
  "artifacts": [
    {
      "binding": "ARTIFACTS",
      "namespace": "default"
    }
  ]
}

This exposes Artifacts as env.ARTIFACTS inside your Worker.

If you are using TypeScript, regenerate your local binding types:

npx wrangler types

Wrangler adds an Artifacts type to your generated worker-configuration.d.ts file.

3. Write your Worker

Replace src/index.ts with the following code:

src/index.js
export default {
  async fetch(request, env) {
    const url = new URL(request.url);


    if (request.method === "POST" && url.pathname === "/repos") {
      // Read the repo name from the request body so the route is reusable.
      const body = await request.json().catch(() => ({}));


      const repoName = body.name ?? "starter-repo";


      // Create the repo and return the remote URL plus initial write token.
      const created = await env.ARTIFACTS.create(repoName);


      return Response.json({
        name: created.name,
        remote: created.remote,
        token: created.token,
      });
    }


    return new Response("Use POST /repos to create an Artifacts repo.", {
      status: 405,
      headers: { Allow: "POST" },
    });
  },
};

This Worker creates an Artifacts repo and returns the remote URL and token your Git client needs to push and pull.

For the demo, the Worker returns the initial write token. In production, mint short-lived read tokens for clone and pull flows, and mint write tokens only for operations that need push access.

4. Invoke your Worker to create a repo

Start local development:

npx wrangler dev

Then, open a second terminal and send a request to your Worker to create a new Artifacts repo:

Terminal window
curl http://localhost:8787/repos \
  --header "Content-Type: application/json" \
  --data '{
    "name": "starter-repo"
  }'

Your Worker will call env.ARTIFACTS.create() and return three values you will need for Git operations:

{
  "name": "starter-repo",
  "remote": "https://<ACCOUNT_ID>.artifacts.cloudflare.net/git/default/starter-repo.git",
  "token": "art_v1_0123456789abcdef0123456789abcdef01234567?expires=1760000000"
}
  • name: the repo name. Must be unique within the namespace.
  • remote: the Git remote URL for this repo. <ACCOUNT_ID> will be your actual Cloudflare account ID.
  • token: a short-lived credential for Git operations. The token encodes its expiry directly in the ?expires= suffix as a Unix timestamp.

Copy the remote and token values into local shell variables:

Terminal window
export ARTIFACTS_REMOTE="<PASTE_REMOTE_FROM_RESPONSE>"
export ARTIFACTS_TOKEN="<PASTE_TOKEN_FROM_RESPONSE>"

5. Push your first commit with git

In the previous step, your Worker created an empty Artifacts repo. Now you will create a local Git repo, add a file, and push it to Artifacts — the same way you would push to any Git remote.

Terminal window
mkdir artifacts-demo
cd artifacts-demo
git init -b main
printf '# Artifacts demo\n' > README.md
git add README.md
git commit -m "Initial commit"
git remote add origin "$ARTIFACTS_REMOTE"
git -c http.extraHeader="Authorization: Bearer $ARTIFACTS_TOKEN" push -u origin main

The -c http.extraHeader flag passes the token as a request header, which keeps it out of your Git config and shell history.

If you need a self-contained remote URL for a short-lived command, build one from the token secret instead:

Terminal window
export ARTIFACTS_TOKEN_SECRET="${ARTIFACTS_TOKEN%%\?expires=*}"
export ARTIFACTS_AUTH_REMOTE="https://x:${ARTIFACTS_TOKEN_SECRET}@${ARTIFACTS_REMOTE#https://}"
git push "$ARTIFACTS_AUTH_REMOTE" HEAD:main

6. Pull the repo with a regular Git client

Clone the same repo into a second directory:

Terminal window
cd ..
git -c http.extraHeader="Authorization: Bearer $ARTIFACTS_TOKEN" clone "$ARTIFACTS_REMOTE" artifacts-clone
git -C artifacts-clone log --oneline -1

You should see the commit you pushed in the previous step.

You can also clone with a self-contained remote URL for a short-lived command:

Terminal window
git clone "$ARTIFACTS_AUTH_REMOTE" artifacts-clone

7. Deploy your Worker

Switch back to your Worker project directory:

Terminal window
cd artifacts-worker

Deploy the Worker so you can create repos without running wrangler dev:

npx wrangler deploy

Wrangler prints your workers.dev URL. Use the same curl request against that URL to create additional repos from production.

Next steps

Workers binding reference Review the binding surface, return types, and method-by-method examples.
Best practices Use repo isolation, least-privilege tokens, and namespace separation effectively.
Git protocol Use standard git-over-HTTPS remotes with either URL-based auth or `http.extraHeader`.
