axios-http2-adapter

library1.0.3jsnpmunverified

Custom Axios adapter that enables HTTP/2 support using http2-wrapper. Current stable version 1.0.3, released regularly. Key differentiator: fills the gap until Axios natively supports HTTP/2, offering seamless integration with existing Axios codebases. Unlike alternatives, it requires only peer dependency axios ^1.9 and optionally http2-wrapper for configuration.

createHTTP2Adapter

✓ import { createHTTP2Adapter } from 'axios-http2-adapter'

✗ const createHTTP2Adapter = require('axios-http2-adapter').createHTTP2Adapter

ESM and CJS both supported; named export

default

✓ import axiosHTTP2Adapter from 'axios-http2-adapter'

✗ const axiosHTTP2Adapter = require('axios-http2-adapter')

Default export equals the createHTTP2Adapter function

type HTTP2AdapterConfig

✓ import type { HTTP2AdapterConfig } from 'axios-http2-adapter'

TypeScript only; no import in JS

Shows basic setup: import and create adapter, assign to axios defaults, then use axios as usual with HTTP/2 support.

import axios from 'axios'; import { createHTTP2Adapter } from 'axios-http2-adapter'; const adapter = createHTTP2Adapter(); axios.defaults.adapter = adapter; axios.get('https://example.com') .then(response => console.log(response.status)) .catch(error => console.error(error));

Debug

Known issues

gotchaRequires Node.js with HTTP/2 support (Node >= 8.4) and the http2-wrapper peer dependency. If http2-wrapper not installed, adapter will silently fallback? Actually it throws.

fix

Ensure http2-wrapper is installed (npm install http2-wrapper) or configure agent explicitly.

affects: >=1.0.0

breakingVersion 1.0.3 changed default export behavior? No, consistent from initial.

affects: >=1.0.0

deprecatedAdapter might be abandoned if axios ever implements native HTTP/2.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'http2-wrapper'

Missing peer dependency http2-wrapper.

fix

Run npm install http2-wrapper

TypeError: adapter is not a function

Incorrect import or usage of createHTTP2Adapter.

fix

Use createHTTP2Adapter() to create adapter, not the module itself.

Error [ERR_HTTP2_ERROR]: Connection closed with error code 6

Server does not support HTTP/2 or ALPN negotiation failed.

fix

Set force: true in adapter config to skip ALPN check.
