next-file-64ify 📁

The "next-file-64ify" package simplifies file handling in Next.js/React.js applications by converting selected files to base64 strings. It provides easy-to-use functions for validating file types and sizes, ensuring smooth and efficient file uploads. It is ideal for image files and integrates seamlessly with React components for streamlined file management.

Installation:

npm i next-file-64ify
# or
yarn add next-file-64ify
# or
pnpm i next-file-64ify

Quick Start:

✔ Simply connect with your Next.js or React.js application 🤝.

"use client";

import React, { useState } from "react";
import { _64ify } from "next-file-64ify";

const MyFileUpload = () => {
 const [myFile, setMyFile] = useState<File | null>(null);

 const handleSubmit = async (e: React.FormEvent) => {
   e.preventDefault();
   if (myFile) {
     const { data, isLoading, isError, isValidSize } = await _64ify(myFile, {
       allowedSizes: {
         minSize: 10,
         maxSize: 2048,
       },
       allowedTypes: ["image/jpeg", "image/png"],
     });
     console.log({ data, isLoading, isError, isValidSize });
   }
 };

 const handleChange = (e: React.ChangeEvent<HTMLInputElement>) => {
   if (e.target.files) {
     setMyFile(e.target.files[0]);
   }
 };

 return (
   <form onSubmit={handleSubmit}>
     <input
       type="file"
       accept="image/jpeg, image/png"
       onChange={handleChange}
     />
     <button type="submit">Upload File</button>
   </form>
 );
};

export default MyFileUpload;

Customizing File Types and Sizes:

✔ 1. Set File Size Limits

const { data, isLoading, isError, isValidSize } = await _64ify(myFile, {
 allowedSizes: {
  minSize: 1024, // file size in KB
  maxSize: 1024 * 5, // file size in MB
 },
 ...
});

✔ 2. Add More Allowed File Types (for the package)

const { data, isLoading, isError, isValidSize } = await _64ify(myFile, {
 allowedTypes: ["image/jpeg", "image/png", "image/webp"],
 ...
});

✔ 3. Update File Input to Accept More Types (for the browser)

<input type="file" accept="image/jpeg, image/png, "image/webp", ..."/>

✔ Most commonly used file types.
