I don't want to use grunt or gulp to compile ts files. I just want to do it in my package.json something like this:
"scripts": { "build": "tsc main.ts dist/" }, is it possible?

Use the ts-node package to run a TypeScript file from the command line, e.g. npx ts-node myDirectory/myFile. ts . The ts-node command will transpile the TypeScript file to JavaScript and run the code in a single step.
As you know, TypeScript files can be compiled using the tsc <file name>. ts command.
The TypeScript compiler compiles these files and outputs the JavaScript with . js extension by keeping the same file name as the individual input file. The TypeScript compiler also preserves the original file path, hence the . js output file will be generated where the input file was in the directory structure.
"build": "tsc main.ts dist/"
Highly recommend you use tsconfig.json and then the -p compiler option to build your code. Look at: Compilation-Context
Here is the setup for using tsc with NPM scripts
init
npm init npm install typescript --save And then in your package.json add some scripts:
"scripts": { "build": "tsc -p .", "start": "npm run build -- -w" }, npm run build npm start Enjoy 🌹

If you want to compile and run, you can use the ts-node module.
npm install --save-dev ts-node npm install --save-dev typescript And run with:
"scripts": { "start": "ts-node index.ts" }, All other typescripts files that index.ts has imported (along with imports from index.ts dependencies) will be compiled and executed.
