taro-fetch-polyfill

library0.5.8jsnpmunverified

W3C fetch() API polyfill for Taro 3+ miniapp frameworks. Current stable version is 0.5.8. Provides a ponyfill that works around the locked global object in miniapps, allowing developers to use the standard fetch() interface instead of Taro's native request API. Ships TypeScript types. Updated infrequently.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

fetch

✓ import { fetch } from 'taro-fetch-polyfill'

✗ import fetch from 'taro-fetch-polyfill'

Named import only; default export does not exist.

Request

✓ import { Request } from 'taro-fetch-polyfill'

✗ const Request = require('taro-fetch-polyfill').Request

ESM import works; CJS require also works but named import is preferred.

Response

✓ import { Response } from 'taro-fetch-polyfill'

Same as Request; named import is correct.

Headers

✓ import { Headers } from 'taro-fetch-polyfill'

Same as Request; named import is correct.

Shows basic fetch usage with JSON parsing and error handling.

import { fetch } from 'taro-fetch-polyfill'; fetch('https://api.github.com') .then(response => response.json()) .then(console.log) .catch(err => console.error(err));

Debug

Known issues

gotchaCannot polyfill globally because miniapps lock the global object. Use ponyfill imports only.

fix

Import { fetch } from the package instead of expecting window.fetch or globalThis.fetch.

affects: >=0.0.0

gotchafetch behavior may not fully match browser Fetch API; limited by miniapp runtime capabilities.

fix

Test thoroughly; some features like streaming or abort may not work.

affects: >=0.0.0

deprecatedPackage is unmaintained; no updates since 2021.

fix

Consider alternatives or fork the project.

affects: >=0.5.8

Errors

Common errors & fixes

import { fetch } from 'taro-fetch-polyfill'; TypeError: Cannot read properties of undefined (reading 'fetch')

Using default import instead of named import.

fix

Use named import: import { fetch } from 'taro-fetch-polyfill';

ReferenceError: fetch is not defined

Trying to use fetch globally via polyfill; miniapps don't support global polyfill.

fix

Import fetch as a ponyfill: import { fetch } from 'taro-fetch-polyfill'; then call fetch() directly.

Module not found: Can't resolve 'taro-fetch-polyfill'

Package not installed or missing peer dependency @tarojs/taro.
