React – Dynamically Import Components

I think there may have been some confusion as to what I was trying to achieve. I managed to solve the issue I was having and have shown my code below which shows how I solved it. Separate File (ComponentIndex.js): let Components = {}; Components[‘Component1’] = require(‘./Component1’).default; Components[‘Component2’] = require(‘./Component2’).default; Components[‘Component3’] = require(‘./Component3’).default; export default … Read more

Is it possible to serve Static files with create-react-app from public folder?

Yes, you can place assets in the static folder. Docs: Using the Public Folder You can reference the path in index.html with %PUBLIC_URL%/path/resource.

If these are javascript assets, the build will not be … Read more

Relative import from parent directory

Edit: Relative import paths are not the way to go in Go. Lack of documentation shows something about popularity of relative paths, and I don’t see a reason for using them. Go’s recommended code organization works pretty well. Every package should have a unique import path and be imported everywhere using that same import path. … Read more

ES6 import from root

Had the same issue with React. So i wrote some plugin for babel which make it possible to import the modules from the root perspective – the paths are not shorter – but it’s clear what you import. So instead of: import ‘foo’ from ‘../../../components/foo.js’; You can use: import ‘foo’ from ‘~/components/foo.js’; Here is the … Read more

Module imports and __init__.py

A couple things you could do to improve your organization, if only to adhere to some popular Python conventions and standards. If you search this topic, you will inevitably run across people recommending the PEP8 guidelines. These are the de facto canonical standards for organizing python code. Modules should have short, all-lowercase names. Underscores can … Read more
