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 🙏

Easy Scaffold

Простой инструмент для кодогенерации

Установка

npm install -g easy-scaffold

Использование

Создаём конфиг-файл:

exports.getConfig = function getConfig (args) {
    return {
        entities: [
            { input: './template.ejs', output: '@/result.txt' },
        ],
    };
};

Создаём один или несколько шаблонов в формате ejs:

const <%- name %> = <%= value %>;

Конструкция <%- myVarName %> вставляет значение, эквивалентное myVarName.toString() Конструкция <%= myVarName %> вставляет значение, эквивалентное JSON.stringify(myVarName) Запускаем, указывая конфиг-файл первым аргументом, а переменные - именованными параметрами:

easy-scaffold ./templates/crud/index.js --name myVar --otherParam 123

Если переменные не указаны в параметрах запуска - они будут запрошены в командной строке

Программный вызов

const scaffold = require('easy-scaffold');

scaffold('путь до конфиг-файла', {...параметры}, 'директория исполнения (опционально)')
    .then(() => console.log('Успешно'))
    .catch(e => console.error(e));

Дополнительные возможности

В конфиг-файле можно указать преобразователь данных:

exports.getConfig = function getConfig (args) {
    return {
        entities: [
            { input: './template.ejs', output: '@/result.txt' },
        ],
        data: function data () {
            return {
                full_name: args.first_name + ' ' + args.last_name,
                ...args
            };
        },
    };
};

В шаблонах и конфиге у любой переменной есть свойства для преобразования кейсов. Например, такой шаблон:

const camelCase = <%= someStr.camelCase %>;
const snakeCase = <%= someStr.snakeCase %>;
const kebabCase = <%= someStr.kebabCase %>;
const lowerCase = <%= someStr.lowerCase %>;
const upperCase = <%= someStr.upperCase %>;
const constCase = <%= someStr.constCase %>;
const classCase = <%= someStr.classCase %>;

вернёт такой результат:

const camelCase = "someValueEee";
const snakeCase = "some_value_eee";
const kebabCase = "some-value-eee";
const lowerCase = "some value eee";
const upperCase = "SOME VALUE EEE";
const constCase = "SOME_VALUE_EEE";
const classCase = "SomeValueEee";
