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 🙏

Template helper functions for cookbook variable resolution - string2file, file2string, and more

Readme

@onlineapps/cookbook-template-helpers

Template helper functions for cookbook variable resolution. Helper functions enable data transformations directly in cookbook template variables.

Installation

npm install @onlineapps/cookbook-template-helpers

Overview

Helper functions can be used in cookbook template variables using the syntax:

{{helper_name(argument)}}

Available Helpers

normalizeString

Removes nebezpečné / ne-print znaky, ponechá písmena (včetně diakritiky), čísla, mezery a základní interpunkci. Zachová diakritiku a case.

Signature:

function normalizeString(value)

webalizeString

Normalizuje řetězec pro URL/slug: odstraní diakritiku, interpunkci, nahradí mezery pomlčkami, převede na lowercase, zkolabuje vícenásobné pomlčky.

Signature:

function webalizeString(value)

string2file

Převede string nebo inline descriptor na file descriptor (přes ContentResolver). Ukládá do storage podle nastavení ContentResolveru.

Signature:

async function string2file(input, context)

file2string

Převede file/inline descriptor na string (přes ContentResolver). File stáhne z MinIO, inline vrátí přímo.

Signature:

async function file2string(descriptor, context)

Usage in Cookbook

Helpers jsou k dispozici při resolvování template proměnných:

{
  "input": {
    "title": "{{normalizeString(api_input.title)}}",
    "slug": "{{webalizeString(api_input.title)}}",
    "file": "{{string2file(api_input.content)}}",
    "content": "{{file2string(steps.prepare.output.file_descriptor)}}"
  }
}

Integration

Helper functions are passed to the cookbook executor:

const templateHelpers = require('@onlineapps/cookbook-template-helpers');
const { CookbookExecutor } = require('@onlineapps/cookbook-executor');

const executor = new CookbookExecutor(cookbook, {
  helpers: templateHelpers
});

Adding Custom Helpers

You can combine global helpers with custom helpers:

const templateHelpers = require('@onlineapps/cookbook-template-helpers');
const customHelpers = require('./customHelpers');

const allHelpers = {
  ...templateHelpers,
  ...customHelpers
};

const executor = new CookbookExecutor(cookbook, {
  helpers: allHelpers
});

Helper Function Requirements

  • Deterministic: Stejný vstup = stejný výstup
  • Bez vedlejších efektů: String helpery jsou čisté; file helpery používají ContentResolver
  • Chyby: Měly by být jasné a srozumitelné

Dependencies

  • @onlineapps/content-resolver (pro string2file/file2string)
