New Project

Tips for initializing new blank projects

Typescript Environment

Basic environment for executing Typescript scripts.

Commands & Configs

Initialize Node Project

npm init --init-author-name "your-email" -y

Installing TS on Node

Node by default don't recognize Typescript only Javascript.

npm install --save-dev @types/node
npm install --save-dev typescript

Generate the tsconfig.json file:

npx tsc --init \
--outDir build \
--module commonjs \
--allowJs true \
--removeComments true

or for a more strict configuration:

npx tsc --init \
--outDir build \
--esModuleInterop \
--resolveJsonModule \
--module commonjs \
--allowJs true \
--noImplicitAny true \
--removeComments true

You can add these to configure the folders to include and exclude in transpilation:

tsconfig.json

{
    "compilerOptions": {

    },
    "include": ["./src"],
    "exclude": ["./tests"]
}

Configure Custom Running Commands

To be executed with npm.

# For Windows only (To execute the removal files/folders)
npm install --save-dev rimraf

package.json

{
    "scripts": {
        // If Windows
        "build": "rimraf ./build && tsc",
        // If Linux
        "build": "rm -rf ./build && tsc",
        "test-build": "node build/main.js",
    }
}

The building output directory may be configured in the tsconfig.json file.

Optional: Install nodemon (For Cold Reloading)

To auto reload the project when files change.

npm install --save-dev ts-node nodemon

package.json

{
    "scripts": {      
        "dev": "nodemon --watch src -e ts --exec ts-node src/main.ts"
    }
}

nodemon.json

{
    "watch": ["src"],
    "ext": ".ts,.js",
    "ignore": [],
    "exec": "npx ts-node ./src/main.ts"
}

Optional: Install dotenv (For Env variables)

npm install --save-dev dotenv

nodemon.json

{
    "exec": "npx ts-node -r dotenv/config ./src/main.ts"    
}
