every module and every folder in a monorepo needs to have a package.json and tsconfig.json so bootstrap it accordingly

now common folder contains modules that are used by both client and the server

here in our common folder we will write our zod types

// if you want to create a module and publish it to npm so other people can locally bring using npm install is by npmjs.org website. this is a registry where other people just put their code and allow others to use it

// rule of thumb:: when publishing into npm we don't publish typescript file. publishing ts file to npm means publishing your code to npm

changes in package.json : "name": "@mohmmed_aariz/common", "main": "dist/index.js",

to publish code

1. npm login

2. npm publish --access=public

3. npm pack // to show what files you published ie. mohmmed_aariz-common-1.0.0.tgz we see a compressed file which shows what goes to npm here, we see that we have also published .ts file so we can stop uploading it by using .npmignore file same as .gitignore

4. now we can run npm install @mohmmed_aariz/common in our repositiory then it will still work

// now to integrate it to our application we do npm install in both client and server

• .d.ts is a declaration file it gives just the types of the code. not actual js code neither complete ts file which has both js and ts so to create it go to tsconfig.json and make declaration true here

now, dist has two files:: - .js and .d.ts here .d.ts just contain all the declaration and no js code which can be executed
