Getting Started with common-comp-lib

A library of React components created using create-react-app.

Steps to Create common-comp-lib

run the below commands

1.npx create-react-app common-comp-lib

2.cd common-comp-lib

3.remove everything from src folder

4.add src/index.js

import React from 'react'; import ReactDOM from 'react-dom'; ReactDOM.render( Hello World, document.getElementById('root') );

5.add src/lib

In this folder add your library components

6.Additinally add src/lib/utils

In that add isEmpty method for conditionally rendering. export const isEmpty = (value) => { return ( value === undefined || value === null || (typeof value === "object" && Object.keys(value).length === 0) || (typeof value === "string" && value.trim().length === 0) ); };

7.Install babel-cli using the command npm i babel-cli --save-dev and create a file .babelrc in the root of the project with the following contents:

{ "presets": ["@babel/preset-env", "@babel/preset-react"] }

8.Replace the build script inside package.json with the following:

"build": "NODE_ENV=production babel src/lib --out-dir dist --copy-files --ignore tests,spec.js,test.js,snapshots"

9.The command npm run build will now transpile the code inside src/lib (ignoring tests and snapshots) into the folder dist.

10.Remove the line "private": true from package.json. Also remove react-scripts, react and react-dom from dependencies, and move them to devDependencies. Additionally, you can also add react and react-dom to peerDependencies.

11.To prepare for publishing, add the following lines to package.json:

"main": "dist/index.js", "module": "dist/index.js", "files": [ "dist", "README.md" ], "repository": { "type": "git", "url": "URL_OF_YOUR_REPOSITORY" }

12.Remove the default README.md file, and create a new one with some information about the library.

13.Publish to npm!

npm publish
