Elm-debug-decoders NPM

elm-debug-decoders

A tool for debugging decoders in Elm. This tool allows you to easily tell which decoders passed on the data you give it via a web UI.

Install

This package requires elm-interface-to-json to be installed globally.

npm install -g elm-interface-to-json
npm install -g elm-debug-decoders

Usage

This tool will generate an Elm file inside the directory you specifiy. It will use your elm-package.json in order to look up which decoders to pull things in from. Make sure to run elm-make in the directory prior to running elm-debug-decoders.

elm-make example/Main.elm

# Load the decoders in the example dir's elm-package.json
elm-debug-decoders --path example/

# Load the ones in the current directory
elm-debug-decoders

You then need to open the DebugDecoders.elm file inside elm-reactor, and paste your JSON into the text field!

It will also go through and find all the views you have that take in data that you have a decoder for. You may need to temporarily expose all your views in order to use this!
