@ublitzjs/payload package for receiving request payloads

This module provides you with efficient utilities to simplify accumulating payload and receive multipart requests (busboy under the hood).

parseFormDataBody

This utility lets you parse multipart/form-data and application/x-www-form-urlencoded

import {registerAbort} from "@ublitzjs/core"
import {parseFormDataBody} from "@ublitzjs/payload"
server.post("/", async (res, req)=>{
  registerAbort(res);
  var result = await parseFormDataBody(
    {
      res, CT: req.getHeader("content-type"), 
      outDir: "tmp",
      parseLimits: {
        //busboy limits. If exceeded - reverts all disk changes and return error message
        fileSize: 1024*1024
      }
    }, 
    // mode "memory" | "disk"
    "disk", 
    // whether to accept repeated files/fields
    false
  );
  if(!result.ok) {
    // all saved files get auto-deleted
    // errCode as "400" | "500" (if disk failed)   
    if(!res.aborted) return res.writeStatus(res.errCode).end(res.data) // as string, error message
  }
  console.log("Files data", result.data.files)
  console.log("Fields", result.data.fields)
  res.end("OK")
})

accumulateBody

Manually writing "res.onData" handling annoys, that's why here is a solution.

import {accumulateBody} from "@ublitzjs/payload"
import {registerAbort} from "@ublitzjs/core"
server.post("/", async (res, req)=>{
  var CL = Number(req.getHeader("content-length"))
  if(CL > yourMaxBody) return res.writeStatus("413").end("too large")
  var result = await accumulateBody(res, CL) //CL lets preallocate memory
  if(res.aborted) return;
  console.log("Got payload", result.toString())
})
