Unable reach Vite dev server with start-server-and-test and axios

[sonicoder86]

Describe the bug

When I start my development server with Vite, it works completely fine in the browser, but querying it with axios like this axios.get('http://localhost:3000') or with the start-server-and-test package it results in 404 responses.

Here are the headers sent:

       _header: 'GET / HTTP/1.1\r\n' +
        'Accept: application/json, text/plain, */*\r\n' +
        'User-Agent: axios/0.21.1\r\n' +
        'Host: localhost:3000\r\n' +
        'Connection: close\r\n' +
        '\r\n',

Reproduction

It's reproducible in my repository https://github.com/blacksonic/vue-3-playground by running npm run test:e2e:javascript or starting the dev server with npm start and running node ./axios.js. Both cases return 404 errors.

• vite version: 2.0.0-beta.56

axios defaults to accept only JSON and plain text. Set your accept header to include text/html.

[sonicoder86]

Is it a Vite specific setting not to accept text/plain? It works with Rollup/Webpack by default in my other repo https://github.com/blacksonic/todomvc-svelte.

I don't know if its a missing feature or a decision not to support it.

[sonicoder86]

I don't know where should it be in the codebase, but I would happily contribute it if it fits the repo.

[yyx990803]

It's an explicit decision because text/plain may need to go through the resolve/transform pipeline. Only text/html is exempt.

[dbousamra]

Can confirm upgrading to later version fixes this.

@dbousamra there was a fix in start-server-and-test but you still have to write http-get://localhost:3000 instead of http ://localhost:3000
