Upload Middleware in Vkrun

Introduction

The Upload middleware in Vkrun provides a powerful solution for handling file uploads in your application. It supports both disk and memory storage and includes built-in validation for file size, type, and other constraints. This middleware is designed to work seamlessly with the parseData middleware for handling multipart/form-data requests.

Features:

Supports single and multiple file uploads.
Disk and memory storage options.
Customizable file validation for size, extensions, and required fields.
Custom error handling for upload constraints.

Quick Start

import v from "vkrun"
 
const app = v.App()
app.use(v.parseData())
 
const upload = v.upload.diskStorage({
  destination: "./uploads",
  filename: (file) => `custom-${file.fieldName}-${Date.now()}.${file.extension}`
}).singleFile({
  fieldName: "file",
  required: { enable: true },
  size: { value: 5000000 }, // 5MB
  extensions: { value: ["png", "jpg"] }
})
 
app.post("/upload", upload, (req, res) => {
  res.status(200).json({ message: "File uploaded successfully!", file: req.files })
})
 
app.server().listen(3000, () => {
  console.log("Server is running on port 3000")
})
