babel-proxy-server

A proxy server which converts js files in commonjs or esm modules to amd modules.

The purpose of this service is to load code from https://github.com/cheminfo-js/visualizer-helper into visualizer views with the proper module format.

Running the proxy locally

First cp .env.example .env and edit it (following instructions in the file).

npm start

How to test your changes in the visualizer?

Run the proxy locally as described above, then set the vh alias to be http://localhost:9898/cheminfo-js/visualizer-helper in the general configuration of your view.

Options

--proxyTarget

The URL the proxy should serve. The url can be a file URL and it will serve files from the local file system. Within that location, any files which match the visualizer-helper pattern are transpiled with babel and transformed into AMD modules. Any other files are served as is.

default: parent git directory relative to where you cloned this repository.

# Server local files
node src/server.js --proxyTarget=file:///Users/xyz/git/

# Serve remote http endpoint
node src/server.js --proxyTarget=https://raw.githubusercontent.com

--noBabel

Use it only as a proxy, don't transpile

default: false

Additional proxies

You can configure additional simple proxies using the a json configuration file.

Set the PROXY_CONFIG_FILE environment variable to point the configuration file. See this file as example.
