Create a feature folder from an existing feature folder

readme.md

This script is to use when you duplicate a module.

For example, lets say you have all the crud basic feature for user and you would like to seed the feature product with it.

You'll have to copy "user" into "product", search and replace every file:

• replace "user" by "product"
• and "User" by "Product"
• and "USER" by "PRODUCT"
• and rename files XXX_USER.py to XXX_PRODUCT.py
• and UserXXX.js to ProductXXX.js
• and createUser.tsx to createProduct.tsx
• and rename the folder userLibs to productLibs etc...

Install

You'll need to have Nodejs installed. Copy this script in a folder in your path, make it executable and you should be good to go.

curl https://gist.githubusercontent.com/debrice/83e3740eb20be24bb95f8b179d3a4503/raw -o /usr/local/bin/fromModule
chmod +x /usr/local/bin/fromModule

Usage

this script takes care of that in just 3 lines:

cp -r user product
cd product
fromModule user product

fromModule.js

#!/usr/bin/env node
