Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

FileUploader

File upload support for multiple storage backends provides flexibility by allowing uploads to be handled across different platforms like local filesystems, AWS S3, or Google Cloud Storage. This feature ensures secure, scalable, and efficient file storage tailored to users' needs.

Features

  • Middleware for handling file uploads in Express.
  • Support for multiple file storage backends (local filesystem, AWS S3, Google Cloud Storage).
  • File validation (size, type, etc.).
  • Chunked uploads for large files.
  • Image processing and resizing utilities.

Installation

npm install file-uploader-js3

Usage

Middleware

const express = require('express');
const { fileUpload } = require('file-uploader-js3');

const app = express();

// Local storage
const upload = fileUpload('local', { destination: 'uploads/' });

app.post('/upload', upload.single('file'), (req, res) => {
  res.send('File uploaded successfully');
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

// AWS S3 storage
const upload = fileUpload('s3', {
  bucket: 'your-bucket-name',
});

app.post('/upload', upload.single('file'), (req, res) => {
  res.send('File uploaded successfully');
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

// Google Cloud Storage (GCS) storage
const upload = fileUpload('gcs', {
  bucket: 'your-bucket-name',
});

app.post('/upload', upload.single('file'), (req, res) => {
  res.send('File uploaded successfully');
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});

File Validation

const { validateFile } = require('file-uploader-js3');

const options = {
  maxSize: 1024 * 1024, // 1 MB
  allowedTypes: ['image/jpeg', 'image/png'],
};

try {
  validateFile(req.file, options);
  // Continue processing the file
} catch (error) {
  res.status(400).send(error.message);
}

Image Processing

const { resizeImage } = require('file-uploader-js3');
const fs = require('fs');

const buffer = fs.readFileSync('path/to/image.jpg');

resizeImage(buffer, 200, 200)
  .then((resizedBuffer) => {
    fs.writeFileSync('path/to/resized_image.jpg', resizedBuffer);
  })
  .catch((error) => {
    console.error(error);
  });
