Just to be clear, you expect ctx.body = Buffer.from(...)
to result in a response body as:
{
"type":"Buffer",
"data":[116,101,115,116]
}
Because that's super opinionated? Koa doesn't do anything special when body is set to a buffer. This is how node:http works.
from koa.
Hello @AlcaYezzz,
Koa doesn't do anything special, you should try this to get the behavior you're hoping for:
const fooFunction = async (ctx: Context) => {
// ...
ctx.body = Buffer.from('test').toJSON()
return ctx
}
from koa.
I can only show you the door, you're the one who have to walk through it.
import {PassThrough, Readable} from 'node:stream'
function * _generate() {
yield 'test'
}
async function _stream(ctx) {
const stream = Readable.from(_generate())
ctx.type = 'application/octet-stream'
ctx.response.set('content-disposition', 'attachment; filename="via_stream.txt"')
ctx.body = stream.pipe(new PassThrough())
}
async function _json(ctx) {
ctx.response.set('content-disposition', 'attachment; filename="via_json.json"')
const _data = []
for (const data of _generate()) {
_data.push(data)
}
ctx.body = {
type: 'Uint8Array',
data: [...(new globalThis.TextEncoder().encode(_data.join('')))],
}
}
Using @koa/router
:
GET /json
curl -vJO 'http://localhost:5001/json
cat via_json.json
// => {"type":"Uint8Array","data":[116,101,115,116]}
GET /
curl -vJO 'http://localhost:5001/
cat via_stream.txt
// => test
from koa.
Koa does something special in case body is set to a buffer. Changes the content type to bin.
