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 🙏

Readme

Data Factory

Reaction Data Factory creates a simple fixture factory from SimpleSchema definitions for testing and seeding applications.

Install

npm install @reactioncommerce/data-factory

Usage

Adding schemas to the Factory object.

import SimpleSchema from 'simpl-schema';
import { createFactoryForSchema } from "@reactioncommerce/data-factory";

const Example = new SimpleSchema({
  strProp: String,
  boolProp: Boolean,
});
createFactoryForSchema("Example", Example);

Creating mock data structures.

import { Factory } from "@reactioncommerce/data-factory";
const mockExample = Factory.Example.makeOne();
// mockExample output
// { _id: "e02993ea96d7", strProp: "mockStrProp", boolProp: true }

const mockExamples = Factory.Example.makeMany(2);
// mockExamples output
// [{ _id: "e02993ea96d7", strProp: "mockStrProp", boolProp: true }, { _id: "3ff4e0634ecc", strProp: "mockStrProp", boolProp: false }]

Creating mock data with custom property values.

const mockExample = Factory.Example.makeOne({ strProp: "Custom Value" });
// mockExample output
// { _id: "e02993ea96d7", strProp: "Custom Value", boolProp: true }

Creating mock data with custom property function.

const mockExamples = Factory.Example.makeMany(3, { _id: (i) => (i + 100).toString() });
// mockExamples output
// [{ _id: "100", strProp: "mockStrProp", boolProp: true }, { _id: "101", strProp: "mockStrProp", boolProp: false }], { _id: "102", strProp: "mockStrProp", boolProp: false }]

Mock Values

When you call makeOne or makeMany, a full document (including all nested schemas recursively) is automatically built based on the schema. The value of each node is determined like this:

  • If mockValue is found in the schema definition, use that value. mockValue is not part of normal SimpleSchema but is added by and checked by this package.
  • If defaultValue is found in the schema definition, use that value.
  • If autoValue is found in the schema definition, use it to get a value.
  • If allowedValues is found in the schema definition, use a random item from the array as the value.
  • If all else fails, use faker.js to generate a random value of the type specified in the schema definition. For Number fields, the min and max values are respected when generating a random number. For String fields, the regEx value will be used if it matches one of the SimpleSchema.RegEx.*

Thanks

Thanks to @MaxGuitet and the team at Cambridge Software for their work on simpl-schema-mockdoc that heavily influenced this package.
