export-helper

export-helper

Rather pretentious name for a tiny nodejs module that edits the last line of a file. It turns export = myModule; into default export myModule; between tsc compilations (both ways supported).

Compatibility

node >= 10

Install

npm install export-helper

Use

// helper.js
const exportHelper = require("export-helper");

exportHelper({ mode: "es6", path: "testFile.ts" })
  .then(res => res);

In terminal:

$ node helper.js
$ npmjs/export-helper: "export = constant;" has successfully be replaced by "export default constant;" (testFile.ts)

Options

This function accepts an option object :

const options = { 
  mode: "es6", // available options: "es5", "es6"
  path: "testFile.ts", // path to file (no need ./)
  silent: false, // pass it to true to silent the console.log; false by default
  linesToTrim: 1 /* default to 1;
    you usually don't need to touch this, but if your IDE puts an extra blank line 
    between your module export and EOF, pass it to 2 and it should do the trick.
   */
};

Interpolate something like the node helper.js shown above between them to alter your source code between two tsc calls.

The goal is to generate stuff that can be imported with either require("module") or import module from "module.

In other words, this is to avoid asking people to require("module").default your module when they're just fine with the syntax of Old.

Originally built for another module, this is a link to the tsconfig-cjs.json file.

WIP, USE AT YOUR OWN PERIL !!!!!!!!!
