Scope UI

Getting Started (using local node)

• You need nodejs 4.2.2 and a running weavescope container
• Setup: npm install
• Develop: BACKEND_HOST=<dockerhost-ip> npm start and then open http://localhost:4042/

This will start a webpack-dev-server that serves the UI and proxies API requests to the container.

Getting Started (using node in a container)

• You need a running weavescope container
• Develop: make WEBPACK_SERVER_HOST=<dockerhost-ip> client-start and then open http://<dockerhost-ip>:4042/

This will start a webpack-dev-server that serves the UI from the UI build container and proxies API requests to the weavescope container.

Test Production Bundles Locally

• Build: npm run build, output will be in build/
• Serve files from build/: BACKEND_HOST=<dockerhost-ip> npm run start-production and then open http://localhost:4042/

Coding

This directory has a .eslintrc, make sure your editor supports linter hints. To run a linter, you also run npm run lint.

Logging

To enable logging in the console, activate it via localStorage in the dev tools console:

localStorage["debug"] = "scope:*"

The Scope UI uses debug for logging, e.g.,:

const debug = require('debug')('scope:app-store');
debug('Store log message');

Gotchas

Got a blank screen when loading http://localhost:4042?

Make sure you are accessing the right machine: If you're running npm start on a virtual machine with IP 10.0.0.8, you need to point your browser to http://10.0.0.8:4042. Also, you may need to manually configure the virtual machine to expose ports 4041 (webpack-dev-server) and 4042 (express proxy).
