import self issue bug

[bluelovers]

file

./strtable.ts

import * as self from './strtable';
export default self;
console.log(__filename, require.extensions);

cli

ts-node strtable.ts

output

Expected behavior

should only once , even if .js exists

strtable.ts {
  '.ts': [Function],
  '.tsx': [Function],
  '.js': [Function],
  '.json': [Function],
  '.node': [Function] }

Actual behavior:

will load self x2 ( .js + .ts )

strtable.js { '.js': [Function],
  '.json': [Function],
  '.node': [Function],
  '.ts': [Function],
  '.tsx': [Function] }

strtable.ts { '.js': [Function],
  '.json': [Function],
  '.node': [Function],
  '.ts': [Function],
  '.tsx': [Function] }

Can you create a reproduction I can look at? There's no way, from this information you've given me, such behaviour could be replicated.

[blakeembrey]

Still can not be replicated. I can only assume you have both a .js file and a .ts file next to each other, so this is the expected behaviour. .js has priority of .ts, so these are two distinct files and you aren't importing self, you're importing a different file.

Reference:

[bluelovers]

when we use ts-node and import , should use .ts > .js

[blakeembrey]

I disagree. Messing with core node.js expected behaviour is not something I intend to support, and having a behaviour that's different in ts-node vs tsc + node.js goes against the mission of this module.

[bluelovers]

@blakeembrey how about only if xxxx.ts already loaded, than use .ts > .js ?

[blakeembrey]

That’s still altering the behaviour of node somewhat, I would need to override the module resolution logic. Plus it wouldn’t solve anything really for you - node always loads Javascript first, so you’re just pushing the issue to the second file that’s loaded. You can replicate this by putting a file before your “self import” and it’ll show it only loads the JavaScript and never TypeScript.

how about make option?

#649

[blakeembrey]

But why?

[bluelovers]

make sure when we run .ts is new

sometime when .js, not update done or watcher fail for watch and make new .js
