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 🙏

Datalayer-JS

The datalayer-js is a persistent abstraction component of your database that serverless-mysql has prepared instructions for performing common routines such as registering, reading, editing, and removing data.

Highlights

  • Easy to set up (Fácil de configurar)
  • Total CRUD abstraction (Abstração total do CRUD)
  • Create safe models (Crie de modelos seguros)

INSTALLATION AND USAGE

DataLayer-js is available via NPM:

  npm i db-datalayer-js

on the root of the project create a .env file with the following contents.

  DRIVER = mysql
  HOST = <YOUR HOST>
  PORT = 3306
  USER = <YOUR USER>
  PASSWORD = <YOUR PASS>
  DATABASE = <YOUR DATABASE>

then you create a folder named models, create a model like this:

  import DataLayer from "db-datalayer-js";

  class User extends DataLayer {
    constructor() {
        // entity, required, primary and timestamps
        super("users", [], "id", true)
    }
  }

Now you are ready to use the datalayer function :D

DOCS

  • find

    This is a select from your database

    await user.find().fetch() // same: SELECT * FROM users

    example with all params

    await user.find({ 
      entity_nickname: "user",
      columns: ["user.username", "users_roles.name as role"],
      joins: [{
        type: "left",
        table: "users_roles",
        conditions: ["user.role_id = users_roles.id"]
      }],
      where: [
        "user.username = 'teste'"
      ],
      limit: 1,
      group_by: "user.id",
      order_by: "user.id"
    }).fetch(true)
  • findById

    await user.findById(7).
  • create

    await user.create({
      name:  "value",
    }).save()
    
    // Multiple lines insert
    
    await produtos.create([
      {code:"000", name:"teste 1",value: 1.5},
      {code:"001", name:"teste 1", value: null},
    ]).save();
  • update

    await user.update({
      name:  "value",
    })
  • delete

    let current_user = user.findById(4);
    // param is bool, default value is false and it will update your deleted_at column in your database.
    // when is true the method will delete the current_user
    current_user.destroy()
