Install and Configure

To install and configure TypeScript in your project, you need to perform the following steps:

• Initialize npm in your project directory by running the following command:

npm init

• Install TypeScript as a project dependency by running the following command:

npm install --save-dev typescript

• Create a tsconfig.json file in your project directory to specify the compiler options for building your project. For example:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "strict": true,
    "outDir": "./dist",
    "rootDir": "./src"
  },
  "exclude": ["node_modules"]
}

• Compile your TypeScript code using the following command:

tsc

Note: You can also compile individual TypeScript files by specifying the file name after the tsc command. For example:

tsc index.ts

And you’re all set! You can now start writing TypeScript code in your project.
