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 🙏

		}
	]
}

Installation

npm i --save larvitorder

Usage

Initialize

All below instructions require the loading of libraries like something below (db is an instance of larvitdb and log an instance of winston or larvitutils.Log):

const OrderLib = require('larvitorder');
const orderLib = new OrderLib({ db, log })
await orderLib.runDbMigrations();

Add a new order

const order = new orderLib.Order({db});

order.created = '2022-12-01T13:37:00Z'; // Must be ISO-8601
order.fields	= {'firstname': 'Günter', 'lastname': ['Edelweiss', 'Schloffs']};
order.rows	= [{'price': 399, 'name': 'Screw'}, {'price': 34, 'name': 'teh_foo', 'tags': ['foo', 'bar']}];

await order.save();

Load existing order from database

const order = new orderLib.Order({uuid: 'uuid-on-existing-order-in-db', db});

await order.loadFromDb();
// Now order.fields and order.rows is loaded from database

Remove order from database

const order = new orderLib.Order({uuid: 'uuid-on-existing-order-in-db', db});

await order.rm();
// order is now removed from DB

Get orders

const ordersCtx = new orderLib.Orders({db});

const {orders, hits} = await ordersCtx.get();

Filter and limit order list

const ordersCtx = new orderLib.Orders({db});

// Filter and limit order hits
orders.limit = 10;	// Only return 10 orders
orders.offset = 5;	// Skip the 5 first orders
orders.uuids = ['1ebe346e-c05a-11e6-a4a6-cec0c932ce01'];	// Only return orders with these uuids
orders.matchAllFields = {'firstname': 'Abraham', 'lastname': 'Lincoln'};	// Only return orders that have both the fields firstname and lastname that matches
orders.matchAllRowFields = {'productName': 'A4 paper'};	// Only return orders that have rows matching both the row fieldname "productName" and the value "A4 paper"

// Return order fields
orders.returnFields	= ['firstname', 'lastname', 'status'];	// Only return the order fields listed. IMPORTANT! Will return no order fields if not supplied! Because performance.

// Return order row fields
orders.returnRowFields	= ['productName', 'price'];	// Only return the order row fields listed. IMPORTANT! Will return no order row fields if not supplied! Because performance.

const {orders, hits} = await ordersCtx.get();
