axiosist

library1.2.0jsnpmunverified

Convert a Node.js request handler (e.g., Express app) into an Axios adapter for HTTP testing. Version 1.2.0 is the current stable release, built on top of Axios (peer dependency). It offers promise-based testing unlike supertest's callback/stream hybrid, and treats all HTTP status codes as fulfilled to avoid exception handling for 4xx/5xx. Ships TypeScript type definitions. Release cadence is low; last update 2023-12.

default

✓ import axiosist from 'axiosist'

✗ const axiosist = require('axiosist')

ESM-only; CommonJS require() not supported.

createAdapter

✓ import { createAdapter } from 'axiosist'

✗ const { createAdapter } = require('axiosist')

✓ import type axiosist from 'axiosist'

TypeScript type import for module augmentation.

Create an Express app, test it with axiosist GET request, verify status and data.

import express from 'express'; import axiosist from 'axiosist'; const app = express(); app.get('/', (req, res) => res.status(200).send('Hello')); const response = await axiosist(app).get('/'); console.log(response.status); // 200 console.log(response.data); // 'Hello'

Known issues

breakingRequires axios as peer dependency. Incompatible with axios versions <1.0.0.

fix

Install axios@^1.0.0.

affects: >=1.2.0

breakingESM-only; CommonJS require() will fail.

fix

Use import syntax or dynamic import().

affects: >=1.0.0

gotchaAxiosist treats all HTTP status codes as fulfilled. 4xx/5xx responses do not reject the promise.

fix

Use response.status to check for errors.

affects: >=1.0.0

gotchaThe host header is preserved from the request URL, not defaulted to 127.0.0.1.

fix

Explicitly set host header if needed.

affects: >=1.0.0
