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 🙏

Feathers abstract blob store service

Installation

npm install feathers-blob --save

Also install a abstract-blob-store compatible module.

API

import BlobService from 'feathers-blob'

blobService = BlobService(options)

blobService.create(body, params)

where input body is an object with key uri pointing to data URI of the blob.

Optionally, you can specify in the body the blob id which can be the file path where you want to store the file, otherwise it would default to ${hash(content)}.${extension(contentType)}.

Tip: You can use feathers hooks to customize the id. You might not want the client-side to write whereever they want.

returns output 'data' of the form:

{
  [this.id]: `${hash(content)}.${extension(contentType)}`,
  uri: body.uri,
  size: length(content)
}

blobService.get(id, params)

returns output data of the same form as create.

blobService.remove(id, params)

Example

import { getBase64DataURI } from 'dauria';
import AWS from 'aws-sdk';
import S3BlobStore from 's3-blob-store';
import BlobService from 'feathers-blob';

const s3 = new AWS.S3({
  accessKeyId: process.env.AWS_ACCESS_KEY_ID,
  secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
});

const blobStore = S3BlobStore({
  client: s3,
  bucket: 'feathers-blob'
});

const blobService = BlobService({
  Model: blobStore
});

const blob = {
  uri: getBase64DataURI(new Buffer('hello world'), 'text/plain')
}

blobService.create(blob).then(function (result) {
  console.log('Stored blob with id', result.id);
}).catch(err => {
  console.error(err);
});

Should you need to change your bucket's options, such as permissions, pass a params.s3 object using a before hook.

app.service('upload').before({
  create(hook) {
    hook.params.s3 = { ACL: 'public-read' }; // makes uploaded files public
  }
});

For a more complete example, see examples/app which can be run with npm run example.
