I am developing an HTTP driven REST based application where the need of the project is such that I have to receive compressed gzipped JSON data at the server side. There are several modules available which demonstrate to compress response and sending them back but I didn't find anything which shows how to decompress request data received at the server.
It looks like this might work out of the box with koa-bodyparser. Under the hood koa-bodyparser uses co-body to parse the request body and co-body uses the inflate package to inflates the request body before parsing.
The following code:
const koa = require('koa');
const app = new koa();
const bodyParser = require('koa-bodyparser');
app.use(bodyParser());
app.use(function(ctx) {
ctx.body = ctx.request.body.test;
})
app.listen(3000);
and the following request
curl \
-H 'content-type: application/json' \
-H 'Content-Encoding: gzip' \
-XPOST \
--data-binary @data.json.gz \
localhost:3000
with a data.json that was gzipped (raw looks like the below):
{
"test": "data"
}
Everything worked as expected.
