deco-server

deco-server is decofun as a service (DFaaS).

It's a web service that names anonymous functions in a specified JavaScript file, according to their surrounding context (e.g. is it returned from a function?) and line number.

This can be very useful when debugging, particularly if a stack trace has been lost due to a next tick, and all you have to look at is piles of anonymous functions.

decofun.herokuapp.com

deco-server is currently running at http://decofun.herokuapp.com/, the below examples use this address for instant demo satisfation, but you can also install deco-server and run locally.

Usage

Remote scripts

Say we have the following script tag

<script src='http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.js'></script>

We simply prefix the src with a deco server, like so

<script src='http://decofun.herokuapp.com/?addr=http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.js'></script>

Local scripts

Locally hosted scripts can be uploaded to deco-server where they are transformed and cached for 8 hours.

We can upload a script with curl like so

curl -F filedata=@my-script.js http://decofun.herokuapp.com

When the upload is complete, the POST response will be a ':id/:filename', something like the following:

rsxnyf/my-script.js

Once we have this we can alter our script tag, say we have a script tag like this

<script src='/my-script.js'></script>

We simply change it to

<script src='http://decofun.herokuapp.com/rsxnyf/my-script.js'></script>

Hosting locally

To run deco-server locally

sudo npm i -g deco-server
deco-server

This will start a server on port 8080. To specifiy the port do

PORT=9999 deco-server
