What is exprexo

npm.io

exprexo is a zero-configuration command-line javascript server. Think about it like http-server but with dinamic .js files execution alongside of statics.

exprexo allows creating mocks easily and fast. Just run exprexo in any folder containing some paths with a get.js file and open your browser using the same path as the url. Your paths, your API.

Installing globally

Installation via npm:

npm install exprexo -g

This will install exprexo globally so that it may be run from the command line.

exprexo and javascript make the perfect blend

Get started

Basic example, serving a simple JSON

On a terminal, run:

$ mkdir cool-stuff
$ cd cool-stuff

Create a file named get.json that may look as follows:

{
  "hello": "exprexo"
}

For having your exprexo served, run:

$ exprexo . --open

NOTE: The . tells exprexo to serve the same folder it is running on. The --open flag will open a browser at the given url.

Deeper routes

Let's create a deeper endpoint, run:

$ mkdir -p routes/cool/user
$ cd routes/cool/user

Create a file named get.json that may look as follows:

{
  "id": "537",
  "name": "Mr Coffee",
  "nickname": "exprexo"
}

Now run the following and browse http://localhost:9000/cool/users

$ exprexo

NOTE: Notice there is no . argument, exprexo will serve routes folder by default.

And now some javascript!

Create a file named get.js inside routes/cool/user/ that may look as follows:

module.exports = {
  id: Math.floor(Math.random() * 20),
  name: 'Mr Coffee',
  nickname: 'exprexo'
}

NOTE: exprexo will try to serve at first *.js files, then *.json.

Read query params

Modify get.js inside routes/cool/user/ so it may look as follows:

module.exports = function (req, res) {
  const user = {
    id: Math.floor(Math.random() * 20),
    name: req.query.name,
    nickname: 'exprexo'
  }
  res.send(user)
}

Now run the following and open http://localhost:9000/cool/users/?name=cool

$ exprexo

NOTE: exprexo uses the same API as any express middleware. Define req and res as your function arguments and it's done. If you prefer a classic return statement exprexo will send that for you.

What about POST, PUT, PATCH and DELETE?

exprexo got you covered! Noticed how we have been creating get.json or get.js files? exprexo will match any request method to a file with the same method name.

Want a new POST endpoint? Create a post.json or post.js, it's that easy.

You can create the following supported methods:
