Quick start

This tutorial will show you how to get up and running in a few minutes. Check out the concepts page for a more in-depth introduction.

Install the CLI

Install the Codehooks command line interface (CLI), this lets you fully manage your projects from the command line.

npm install codehooks -g

You need Node.js to install the CLI.

Use 'Dev containers' to set up your codehooks development environment

Our CLI requires use of the terminal window, which can sometimes be challenging especially for Windows users. Check out our blog post about how to set up a dev container for simplified and more consistent development environment on all platforms.

Sign up and Log in

Next you need to sign up / log in to your account (it's totally free), in this example we use a Github account. Your browser will open and direct you a secure login page, and there you can return to the CLI - logged in.

coho login

Then choose login method, e.g. Github.

Select option below

❯ Use Github
Use Google

Create project

Lets go forward and create a new project on your account. A project contains the source code for your serverless functions.

coho create myproject

Follow the guide to create a personal or team project type.

Finally change directory to the new project and install the Codehooks standard library.

cd myproject

The coho create command has now created a new project space and generated a unique name for the API, in this example it's named myproject-2b39 and dev. Your account will be the owner of the project. This can be changed later.

Create a serverless JavaScript Codehook

First, in the project directory, install the Codehooks standard open source libraries codehooks-js and codehooks-crudlify.

npm install codehooks-js codehooks-crudlify --save

Next, start your favorite code editor and open the auto generated index.js in your project directory.

* Auto generated Codehooks (c) example
import {app} from 'codehooks-js'
import {crudlify} from 'codehooks-crudlify'

// test route for https://<PROJECTID>
app.get('/', (req, res) => {
res.send('CRUD server ready')

// Use Crudlify to create a REST API for any collection

// bind to serverless runtime
export default app.init();

Save the JavaScript file.

You are now ready to deploy your project.

Deploy the code to the serverless cloud

coho deploy

Example output from the deploy command.

Deploying to Project: myproject-2b39 Space: dev
Deployed Codehook successfully! 🙌

You can now test the automatic REST API with a sample collection, for example users.


Use the coho info --examples command to find your project name, API tokens and working curl examples.

curl shell command - POST a new user
curl --location 'https://<YOUR-PROJECT-NAME>' \
--header 'x-apikey: <YOUR-API-TOKEN-HERE>' \
--header 'Content-Type: application/json' \
--data-raw '{
"name": "Bill",
"email": "[email protected]",
"active": true

Example output from the curl test.

"name": "Bill",
"email": "[email protected]",
"active": true,
"_id": "6421b3e6a3c762051688edf7"

Lets also test a query for the same data we've added.

curl shell command - query users
curl --location 'https://<YOUR-PROJECT-NAME>' \
--header 'x-apikey: <YOUR-API-TOKEN-HERE>' \
--header 'Content-Type: application/json' \

Which returns an array of 1 object from the database.

"name": "Bill",
"email": "[email protected]",
"active": true,
"_id": "6421b3e6a3c762051688edf7"

Our test shows that the automatic REST API is accessible on the /dev/users route, and we can successfully add and retrieve data from the database to the client.



If you want to test out without signing up, you can use the localserver approach.

Self-host with Open source and MongoDB package

You can "eject" a complete backend and self-host it using the codehooks-mongodb NPM package.
