Is the typescript definition exported correctly? about unfetch HOT 8 CLOSED

So if you do import fetch from 'isomorphic-unfetch' then the types work fine, but it fails to run, due to TypeError: isomorphic_unfetch_1.default is not a function

Searching that error, returns the recommendation of doing the following for commonjs modules import fetch = require('isomorphic-unfetch') however, then typescript complains there are no types, as the type definition is done with esmodules in mind, not commonjs modules

As such, I've done the following workaround for it:

import * as fetchImport from 'isomorphic-unfetch'
const fetch = (fetchImport.default || fetchImport) as typeof fetchImport.default

from unfetch.

Still getting this error. Is there a fix for it?

Same problem with [email protected] ([email protected], [email protected], [email protected]):

error TS7016: Could not find a declaration file for module 'unfetch'. '/home/user/Edge/Demo/node_modules/unfetch/dist/unfetch.js' implicitly has an 'any' type.

from unfetch.

@egasimus I don't think that is the same issue. Typescript definitions were added in [email protected], so that is probably why the declaration file can't be found in your case.

Some more info on my issue:

import * as fetch from 'unfetch';
console.log(fetch); // { default: f(), __esModule: true }

import fetch from 'unfetch';
// error TS1192: Module '"node_modules/unfetch/src/index"' has no default export

The last example works if I enable allowSyntheticDefaultImports, but that was not required before.

Yep, just updated to v4 and have same issue. Definitions are definitely incorrect.

from unfetch.

I believe this is due to TypeScript not respecting the .mjs extension.

Not true, just .d.ts is incorrect.

from unfetch.

if you do import fetch from 'isomorphic-unfetch' then the types work fine

What am i missing here? there are no types but just a typeof fetch which resolves to any
