Nuxt File Storage

Easy solution to store files in your nuxt apps. Be able to upload files from the frontend and recieve them from the backend to then save the files in your project.

Features

📁 Get files from file input and make them ready to send to backend
⚗️ Serialize files in the backend to be able to use them appropriately
🖴 Store files in a specified location in your Nuxt backend with Nitro Engine

Quick Setup

Add nuxt-file-storage dependency to your project

# Using pnpm
pnpm add -D nuxt-file-storage

# Using yarn
yarn add --dev nuxt-file-storage

# Using npm
npm install --save-dev nuxt-file-storage

Add nuxt-file-storage to the modules section of nuxt.config.ts

export default defineNuxtConfig({
    modules: ['nuxt-file-storage'],
})

That's it! You can now use Nuxt Storage in your Nuxt app ✨

Configuration

You can currently configure a single setting of the nuxt-file-storage module. Here is the config interface:

export default defineNuxtConfig({
    modules: ['nuxt-file-storage'],
    fileStorage: {
        // enter the absolute path to the location of your storage
        mount: '/home/$USR/development/nuxt-file-storage/server/files',

        // {OR} use environment variables (recommended)
        mount: process.env.mount
        // you need to set the mount in your .env file at the root of your project
    },
})

Usage

Handling Files in the frontend

You can use Nuxt Storage to get the files from the <input> tag:

<template>
    <input type="file" @input="handleFileInput" />
</template>

<script setup>
    // handleFileInput can handle multiple files
    const { handleFileInput, files } = useFileStorage()
</script>

The files return a ref object that contains the files

handleFileInput returns a promise in case you need to check if the file input has concluded

Here's an example of using files to send them to the backend:

<template>
    <input type="file" @input="handleFileInput" />
    <button @click="submit">submit</button>
</template>

<script setup>
const { handleFileInput, files } = useFileStorage()

const submit = async () => {
    const response = await $fetch('/api/files', {
        method: 'POST',
        body: {
            files: files.value
        }
    })
}
</script>

Handling files in the backend

using Nitro Server Engine, we will make an api route that recieves the files and stores them in the folder userFiles

export default defineEventHandler(async (event) => {
    const { files } = await readBody<{ files: File[] }>(event)

    for ( const file of files ) {
        await storeFileLocally(
            file,         // the file object
            8,            // you can add a name for the file or length of Unique ID that will be automatically generated!
            '/userFiles'  // the folder the file will be stored in
        )

        // {OR}

        // Parses a data URL and returns an object with the binary data and the file extension.
        const { binaryString, ext } = parseDataUrl(file.content)
    }

    return 'success!'
})

interface File {
    name: string
    content: string
}

And that's it! Now you can store any file in your nuxt project from the user ✨
