AGworld recommends the use of VisualStudioCode for development.
First of all, download the software from the official website.
Download VisualStudioCode
While it is possible to create add-ons in JavaScript, we also recommend downloading TypeScript, which is recommended by the official Minecraft reference.
TypeScript requires Node.js.

How to install Node.js and TypeScript

1,Install Node.js : First, visit the official Node.js website and download it.
2,Run the installer : Follow the on-screen instructions to proceed with the installation.
3,After installation is completed : After the installation is complete, check to see if the installation has been completed by using a command pronto or in the terminal.

        node -v
      

4,Use npm and install TypeScript : Type the following command to install TypeScript

npm install -g typescript

5,Confirm version : After installation is complete, check the TypeScript version.

tsc -v

5,Install extensions in VisualStudioCode : Search for "TypeScript" in the VS Code Extensions Marketplace and install the "TypeScript and JavaScript Language Features" plugin.
6,Initialization of project : Create a new folder and open it in VS Code.
Next, initialize the TypeScript project by running the following command in Terminal

        npm init -y
npm install typescript --save-dev
npx tsc --init

      

7,Create a TypeScript file for trial and compile : Create a new file and save it with the extension .ts.
Then, compile the TypeScript file by running the following command in the terminal

npc tsc

Now you can start writing your TypeScirpt code. In fact, when you create the add-on, simply set the extension to .ts and start coding.

To begin with, we will use the ". /games/com.mojang".
For Behavioral Packs, development_behavior_packs
For resource packs,development_resource_packs
Open.
Create a new folder.
In the created folder, create manifest.json.

explanation

header

HEADER is the overview section, where you write the pack's name, UUID, and description.
Duplicate UUIDs are not allowed in add-ons. Be sure to assign separate UUIDs to avoid duplicate UUIDs. *Official name of UUID = Universally Unique Identifier

modules

Modules are an essential part of the add-on. This section contains information about the type of content to be included.
For type, specify either "data" (data-related) or "resources" (resource-related).

dependencies

dependencies will be the part used for advanced add-on development (Script API).
This is where you write other add-ons and other modules that the add-on absolutely needs.
Script APIs include @minecraft/server , @minecraft/server-ui , @minecraft/admin , @minecraft/editor.
The UUID in *dependencies will function properly even if it is omitted.
Put different UUIDs in UUID_1 and UUID_2.
