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 🙏

npm version locales

Table of contents

Introduction

Browser

Download latest stable version.

<script src = "dist/constructs.min.js" type = "text/javascript"></script>
<script>
    var constructs = new constructs("de"); // de = locale (fallback locale is "de")

    let uniqFirstName = constructs.name.getFirstName(); // Maik
    let uniqSurName   = constructs.name.getSurName(); // Raschel
    let uniqEmail     = constructs.email.getEmail(); // [email protected]
</script>

NodeJS

Install

npm install constructs-js --save

Usage

const Constructs    =   require('./construct');
let construct      =   new Constructs('de'); // de = locale (fallback locale is "de")

let first_name = constructs.name.getFirstName();
let sur_name   = constructs.name.getSurName();
let email      = constructs.email.getEmail();

Angular 2+

Install

npm install constructs-js --save

Usage

Add the constructs.min.js in the angular.json at the scripts block

{
  "scripts": [
    "node_modules/constructs-js/dist/constructs.min.js"
  ]
}

Test e.g. in the app.component.ts if the script is reachable:

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  constructor() {
    let constructs = window['constructs']('de');
    
    console.log('First name: '+constructs.name.getFirstName());
  }
}

Usage template

constructs.js can generate multiple random data at once based on object templates. These data packages can then be used e.g. for grids or displays.

Example

let template = {
    name: "Example template",
    structure: [
        {
            name: "id",
            mask: "[id]"
        },
        {
            name: "first_name",
            mask: "[name:getFirstName]"
        },
        {
            name: "sur_name",
            mask: "[name:getSurName]"
        },
        {
            name: "name",
            mask: "{first_name} {sur_name}" // Merge field content from {"name": "first_name"} and {"name": "sur_name"}
        },
        {
            name: "birthday",
            mask: "[date(1990-01-01, 1970-01-01)]" // Generate date from 01.01.1970 and 01.01.1990
        },
        {
            name: "age",
            mask: "[diffYearNow({birthday})]" // Returns the difference in years from the field content {"name": "birthday"} returns
        },
        {
            name: "created_date",
            mask: "[datetime]"
        }
    ],
    output: {
        result: "output", // Use for API (Allowed: output, insert)
        type: "json", // Result json object (Allowed: json, xml)
        limit: 5 // Generate 5 items
    }
};

let generatedData = constructs.generateUniqData(template);

console.log(generatedData);

Output

Template

The template scheme is structured as follows and must be maintained.

{
    structure: [
        {
            name: "id", // Field name
            mask: "[id]" // Mask
        }
    ],
    output: {
        result: "output", // Use for API (Allowed: output, insert)
        type: "json", // Result json object (Allowed: json, xml)
        limit: 5 // Generate 5 items
    }
}

Template masks

The mask is always structured according to the scheme

[module:function]

module: Class module function: function call

Function calls can also include parameters that can be processed further.

Several [module:function] can also be listed in the masks.

Prof. Dr. [name:getFirstName] [name:getSurName]

So different masks can be combined in the input mask and normal text can be used.

Other field contents can also be accessed in the masks. For example, one has built a structure that looks like this:

{
    "name": "birthday",
    "mask": "[date]"
},
{
    "name": "age"
    "mask": "[diffYearNow({birthday})]"
}

Then you can see that in the mask at the field age the field content {birthday} is accessed. It doesn't matter where the field is defined in the structure.
