Deploy Your First Function

Go from zero to a live serverless function in under 2 minutes.

1.Install & Login

pip install zmesh-cli
zmesh login

2. Create a Project

mkdir my-api && cd my-api
zmesh init --name "My API"

3. Write a Function

hello.jsJavaScript

exports.handler = async (payload, zmesh) => {
  const name = payload.name || "World";
  return { message: `Hello, ${name}!` };
};

Or in Python:

hello.pyPython

def handler(payload, zmesh):
    name = payload.get("name", "World")
    return {"message": f"Hello, {name}!"}

4. Deploy

zmesh functions deploy ./hello.js
# ✓ Function "hello" deployed successfully
# Slug: hello
# Invoke: zmesh functions invoke hello

5. Test It

CLI

zmesh functions invoke hello --payload '{"name": "zMesh"}'
# { "message": "Hello, zMesh!" }

cURL (Public API)API Key

curl -X POST https://api.zmesh.in/api/functions/hello \
  -H "x-api-key: zb_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"name": "zMesh"}'

Next Steps

Add database access

Use zmesh.db.query() inside your function to read/write data.

Set environment variables

Use zmesh env --set API_KEY=xxx and access via zmesh.env.API_KEY.
