koa-simple-body

koa-simple-body

npm install koa-simple-body

Coherent and consistent body parsing implementation for Koa v2.

Supports multipart, url-encoded and JSON data by default. Check the index.js for the specific MIME types.

Everything it doesn't understand is parsed as plain text.

Usage

Defaults

const Koa = require("koa")
const bodyParser = require("bodyParser")

const app = new Koa()

app.use(bodyParser())

app.use(ctx => {
  // Print fields
  console.log(ctx.request.fields)

  // Print files (formidable)
  console.log(ctx.request.files)
})

That's it!

Extra options

bodyParser({
  useBuffer: true,      // enables parsing text/* as a buffer
  buffer: "50kb",       // max buffer size
  text: "50kb",         // max text size
  json: "100kb",        // max json size
  urlEncoded: "500kb",  // max url-encoded size
  multipart: {
    // Formidable options object (some examples shown)
    maxFieldsSize: 5 * 1024 * 1024, // 5mb

    // Allow array of files with 'multiple' attribute
    multiples: true
  }    
})

Roadmap

2.0

• Add support for bubbling errors to middleware (feedback and suggestions for API encouraged)
• Ensure default size settings are coherent and best defaults
