koajs / json Goto Github PK

Is it possible to customize the serializer?
My applications use BigInt and V8 (just as Chrome) throws a nice:

  TypeError: Do not know how to serialize a BigInt
      at JSON.stringify (<anonymous>)
      at next.then (/Users/damz/Desktop/cfciampino-reloaded/node_modules/koa-json/index.js:50:32)

I'd like to apply a workaround like (see next) when returning my payloads:
tc39/proposal-bigint#146 (comment)

Good jobs guys!

kinda redundant to have both, unless we support header fields or something else... but meh

RT, if the callback param exists, change this to the jsonp?

It would be nice if there was an option for the prettify to happen automatically based on an accept header, something like this:

switch (ctx.accepts('json', 'html', 'text')) {
    json: break;
    html:
    text:
        // pretty print json here
    default: break;
}

The following results in a payload hola and not the json "hola".

import http from 'http';
import koa from 'koa';
import json from 'koa-json';

const app = new koa();
app.use(json());

app.use(ctx => ctx.body = 'hola');

http.createServer(app.callback()).listen(1234);

Current workaround:

app.use(async (ctx, next) => {
    await next();

    if (typeof ctx.body === 'string')
        ctx.body = `"${ctx.body}"`;
});

this is my code

const middlewares = compose([
    favicon(__dirname + '/favicon.ico'),
    bodyParser({formLimit: '5mb'}),
    json(),
    router.routes(),
    router.allowedMethods()
])

app.use(middlewares)

Hello,

koa is a middleware in my scene, I use koa to send HTTP request and then reponse to browser.

here is my code:

var reqHttp = http.request(opt, function(resHttp){
    if (resHttp.statusCode == 200){
        var buf = "";
        resHttp.on('data', function(data) {
            buf += data;
        });
        resHttp.on('end', function(){
            ctx.body = JSON.parse(buf); // throw error: Can't remove headers after they are sent.
        });
    } else {
        ctx.body = {error: -1};
    }
});
reqHttp.write(data);
reqHttp.end();

I just want a like res.json in express for koa...

please help me ?

Module doesn't seem to be working at all for me.

...
app.use(require('koa-json')());

router.get('/test', function *(next) {
  this.body = {test: 'testing'};
});
...

... go to /test, doesn't look pretty.

Digging into the code I see that it doesn't print pretty if this.body is a string, but by the time koa-json code is run JSON seems to have been stringified already. Is my usage wrong or has koa changed how/when it stringifies JSON which means koa-json no longer works?

give me npm access. i'll fix

If route returns null or undefined or an object with a null or undefined property then body/response is empty!

app.use(async (ctx, next) => {
	try {
    	      await next();
    	      ctx.body = null; //empty response
    	      ctx.body = undefined; //empty response
    	      ctx.body = { data: null }; //empty response
    	      ctx.body = { data: undefined }; //empty response
  	}
	catch(error) {
	    	ctx.status = 400;
		ctx.body = error.message || error;
	}
});

I think that the defaults should be the same for both of these. I get that this is an addon, but if one method is better, then why not use that one for both?
