TypeScripts transpiles files which are non-executable

Question

It appears as though TypeScript is transpiling target files that are not executable.

I have to run chmod u+x <file> after transpilation to get the files to become executable.

This is the case, even if they have a hashbang:

#!/usr/bin/env node

How can I tell TypeScript / tsc to create files which are executable?

Answer 1

Changing file's permissions isn't typescript responsibility.

Solution 1. Use a separate step in the build process in your package.json. For example:

{
  "name": "temp",
  "version": "1.0.0",
  "scripts": {
    "build": "tsc && chmod +x build/index.js"
  },
  "dependencies": {
    "typescript": "^2.3.4"
  }
}

Solution 2.

Write TypeScript Language Service Plugin. I think, in your case this is overengineering.
