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 🙏

yaml-validator-typescript

v1.1.2

Published

Yaml validator to test your yaml with a defined model

Readme

yaml-validator-typescript

Coverage Status Testing app Building Publish to npm

yaml-validator-typescript is a way to validate your Yaml file by using a defined model

Installation

$npm install yaml-validator-typescript

or

$yarn add yaml-validator-typescript

Usage

Define your modele

You can set you model as you want. You just need to have properties initialized

If you don't want some property to be tested, you can implement Yaml

class TestOnlyKeys implements Yaml {
    keysToTest: (keyof TestOnlyKeys)[] = ['key1', 'key2'];
    key1: string = '';
    key2: number = 0;
    keyNotToTest: boolean = false;
}

Here only key1 and key2 are tested You can also set some properties optionals:

class Optional implements Yaml {
    keysToTest: string[] = ['valueToHave', 'valueOptional', 'arrayOptional'];
    optionals: Set<string> = new Set(['valueOptional', 'arrayOptional']);
    valueToHave: string = '';
    valueOptional: string = '';
    arrayOptional: {valueYouNeed1: string, valueYouNeed2: boolean}[] = [
        {valueYouNeed1: '', valueYouNeed2: true},
    ];
}

Here valueOptional and arrayOptional are optionals But if arrayOptional is defined, he has to be right

As a command

Set a config file at the root of the project:

import MyClass from './somewhere';
module.exports = {
    structure: new MyClass(),
    files: ['file1.yaml', 'file2.yaml'],
};

Then run the command

{
    "scripts": {
        "valid-yaml": "validate-yaml"
    }
}

If you have not set the files, you can put them in the command

{
    "scripts": {
        "valid-yaml": "validate-yaml file1.yaml file2.yaml"
    }
}

In your code

import MyClass from './somewhere';
const validator = new Validator(new MyClass());
validator.validate('path_of_my_file.yaml').then((errors) => {
    if (errors.length > 0) {
        console.log('I have some issues I need to fix 🙀');
        errors.forEach((error) => {
            console.log(`- ${result}`);
        });
    } else {
        console.log('No Error in this code 💪');
    }
});

You can validate multiple file at the same time with the same validator

import MyClass from './somewhere';
const validator = new Validator(new MyClass());
validator
    .validateMany('path_of_my_file.yaml', 'another_path_of_my_file.yaml')
    .then((results) => {
        files.forEach((file) => {
            console.log(`${file.name}:`);
            if (file.results.length > 0) {
                console.log('I have some issues I need to fix 🙀');
                file.results.forEach((error) => {
                    console.log(`- ${result}`);
                });
            } else {
                console.log('No Error in this code 💪');
            }
        });
    });
