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 🙏

Readme

Build Status

Base64 Indexer

Converts a specified set of files to base64, outputting a JSON file that contains the result of each file.

Useful, for example, when you want to asynchronously load a set of base64 images in a single request.

Installation

npm install base64-indexer
cd base64-indexer
npm install
npm test

Command Line Usage

node main.js --glob=input/*.{gif,jpg,png,svg} --output=output/

The above example converts all .gif, .jpg, .png and .svg images to base64 and outputs a JSON file containing the results of the conversion to output/.

Node Usage

    var indexer = require('base64-indexer');
    indexer({
	    glob: 'input/*.{gif,jpg,png,svg}',
	    output: 'output/',
	    success: function() {
	        console.log('Conversion finished');
	    },
	    error: function(err) {
	        console.log('Conversion error:', err.message);
	    }
    });

The above example converts all .gif, .jpg, .png and .svg images to base64 and outputs a JSON file containing the results of the conversion to output/.

When the process successfully completes the success callback is called and "Conversion finished" is logged to the console.

If the process fails for any reason the error callback will be called instead and the exception message will be logged to the console.

Another Example

Here's an example of how this has been used internally:

var base64indexer = require('./main');

base64indexer({
    glob: './input/*.{gif,jpg,png,svg}',
    outputTransformer: 'dictionary',
    output: './output/',
    nameTransformer: function(input) {
        return input.replace(/(.*?)\.[^.]+/, '$1')
                    .toLowerCase()
                    .replace('_home', '_H')
                    .replace('_away', '_A');
    }
});

Command Line Options

| Option | Description | |----------|-------------| | --output | Relative path to the output directory. Defaults to 'output/' | | --glob | Pattern for matching input files. Defaults to 'input/*.{gif,jpg,png,svg}' | | --outputTransformer | The transformer to use for the output format (verbose or dictionary)| | --nameTransformer | A regex pattern used for name transformation. The new name will be a concatenation of the capture groups. |

Node Options

| Option | Description | |---------|-------------| | output | Relative path to the output directory. Defaults to 'output/' | | glob | Pattern for matching input files. Defaults to 'input/*.{gif,jpg,png,svg}' | | success | Success callback - called after a successful conversion | | error | Error callback - called if an error occurs during conversion | | outputTransformer | The transformer to use for the output format. String or object. Available transformers: verbose or dictionary. | | nameTransformer | A regex pattern or function used for name transformation. If a regex pattern is provided the new name will be a concatenation of the capture groups. If a function is provided the output of the function will be used as the new name. |

Output Transformers

Output transformers change the way the output file is generated. The following transformers are available:

Verbose (Default)

The verbose transformer output data as an array of verbose objects:

[
    { name: 'file1.png', data: '...base 64 data...' },
    { name: 'file2.png', data: '...base 64 data...' },
    { name: 'file3.png', data: '...base 64 data...' }
}

Dictionary

The dictionary transformer outputs data as an dictionary/map:

{
    'file1.png': '...base 64 data...',
    'file2.png': '...base 64 data...',
    'file3.png': '...base 64 data...'
}
