export typescript

[analog fox]

hello lets say for example i have file at folder/src/index.ts which contains
export { demo, test } from '@/doing/stuff'
is it possible to use demo function in a way to just import folder/src/index into my file?

can you elaborate on what exactly you're trying to achieve?

i have file folder/src/index.ts which contains export { demo, test } from '@/doing/stuff' can i import folder/src/index in other file in order to use functions demo and test

[candid parcel]

yes, that's what export is for

that's like, the single thing that statement allows you to do

[analog fox]

alright

This helped me better understand how exports work:

(If I understand it correctly)

Every export is basically a default export

e.g.

exporter.ts

export default { foo: 'bar' }

importer.ts

import GiveAnyName from 'exporter' // default
// { foo: 'bar' }
import { foo } from 'exporter' // destructed
// foo = 'bar'

---

Hint. In JavaScript there is only 'default export':

module.exports = { foo: 'bar' }

i might be confused about what you're trying to get across, but if i have a file named ./exporter.js with this contents:

export default { foo: 'bar' }

and i try to import that via:

import { foo } from './exporter.js'

it doesn't work (at least with standardized ECMAScript modules, not sure about other module systems)

default exports are their own separate thing, and the import { … } from … syntax is not really the same as "destructuring" (though i see the analogy)

I'm sure it works on CommonJS, but let me check if it works iwth ES too.

// exporter
module.exports = { foo: 'bar' }

// importer
const { foo } = require('./exporter.js')

console.log(foo)

You are right

I had no idea

CJS is fundamentally different from ESM. i'm not sure any of this is relevant to just_follow_white_rabbit's original question though (which AFAICT was just confirming that export can be used to re-export stuff?)

[candid parcel]

in cjs, there's only a single export. esm, which ts module syntax is based on, has both default and named exports. esm does exist at runtime.
