[bug] string payload is not json encoded

[damianobarbati]

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}"`;
});

why would you send a string JSON-encoded?

[damianobarbati]

@jonathanong for consistency:

• the whole react application is expecting json responses
• the api documentation is documenting json responses (why having to document an exception?)
• the artillery load testing scripts are expecting json responses (why having to put exception for 1 endpoint returning a string?)
