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

RudderTyper

RudderTyper is a tool for generating strongly-typed RudderStack analytics libraries based on your pre-defined tracking plan spec.

Features

  • Strongly Typed Clients: Generates strongly-typed RudderStack clients that provide compile-time errors, along with intellisense for events and property names, types and descriptions.

  • Analytics Testing and Validation: Lets you validate if your instrumentation matches your spec before deploying to production, so you can fail your CI builds without a manual QA process.

  • Cross-Language Support: Supports native clients for Javascript, Node.js, Android and iOS.

  • RudderStack Tracking Plans: Built-in support to sync your ruddertyper clients with your centralized RudderStack tracking plans.

Get Started

To fire up a quickstart wizard to create a ruddertyper.yml and generate your first client with the specified configuration details, run the following command:

$ npx rudder-typer init | initialize | quickstart

Other Commands

Update

$ npx rudder-typer update | u | *   (default)

This command syncs plan.json with RudderStack to pull the latest changes in your tracking plan and then generates an updated development client.

Build

$ npx rudder-typer build | b | d | dev | development

This command generates a development client from plan.json.

Production

$ npx rudder-typer prod | p | production

This command generates a production client from plan.json.

Token

$ npx rudder-typer token | tokens | t

This command prints the local RudderStack API token configuration.

Version

$ npx rudder-typer version

This command prints the RudderTyper CLI version.

Help

$ npx rudder-typer help

This command prints the help message describing different commands available with RudderTyper.

CLI Arguments

| Argument | Description | | :-------- | :------------------------------------------------------------------------------- | | config | An optional path to a ruddertyper.yml (or a directory with ruddertyper.yml). | | debug | An optional (hidden) flag for enabling Ink debug mode. | | version | Standard --version flag to print the version of this CLI. | | v | Standard -v flag to print the version of this CLI. | | help | Standard --help flag to print help on a command. | | h | Standard -h flag to print help on a command. |

Configuration Reference

RudderTyper stores its configuration in a ruddertyper.yml file in the root of your repository.

How to integrate RudderTyper-generated client with your app?

This section includes steps to integrate your RudderTyper-generated client with your app across different RudderStack SDKs.

Refer to the examples directory for sample integrations with different RudderStack SDKs.

RudderStack Android SDK

  • Import all the files in the client generated by RudderTyper as a package in your project.

  • Then, you can directly make the calls using the RudderTyper client as shown below:

// Import your auto-generated RudderTyper client:
import com.rudderstack.generated.*

  // Issue your first RudderTyper track call!
  RudderTyperAnalytics.with(this).orderCompleted(
    OrderCompleted.Builder()
    .orderID("ck-f306fe0e-cc21-445a-9caa-08245a9aa52c")
    .total(39.99)
    .build()
  );

RudderStack iOS SDK

  • Import your RudderTyper client into your project using XCode.

Note: If you place your generated files into a folder in your project, import the project as a group not a folder reference.

  • Then, you can directly make the calls using the RudderTyper client as shown:
// Import your auto-generated RudderTyper client:
#import "RSRudderTyperAnalytics.h"

// Issue your first RudderTyper track call!
[RSRudderTyperAnalytics orderCompletedWithOrderID: "ck-f306fe0e-cc21-445a-9caa-08245a9aa52c" total: @39.99];

RudderStack JavaScript SDK

There are two ways to get started with RudderTyper in your browser:

1. Using the JavaScript SDK snippet

  • Paste the JavaScript SDK snippet from the RudderStack dashboard to your HTML file.
  • If you use TypeScript, add @rudderstack/analytics-js as a dev dependency.
npm install --save-dev  @rudderstack/analytics-js
  • Run the following command to generate a bundle from the RudderTyper client:
npx browserify analytics/index.js --standalone rudderTyper >  rudderTyperBundle.js
  • For the TypeScript analytics client, add the NPM package tsify as a dependency and run the following command to generate the bundle:
npx browserify analytics/index.ts -p [ tsify ] --standalone rudderTyper >  rudderTyperBundle.js
  • Import your RudderTyper client and send events, as shown:
<script>
  // Here goes the SDK snippet
</script>
<script src="./rudderTyperBundle.js"></script>
<script>
  rudderTyper.setRudderTyperOptions({
    analytics: rudderanalytics,
  });
  rudderTyper.orderCompleted({
    orderID: 'ck-f306fe0e-cc21-445a-9caa-08245a9aa52c',
    total: 39.99,
  });
</script>

See the sample application for reference.

2. Using NPM

Import the RudderTyper-generated client and make the calls if your framework supports them.

// Import RudderStack JS SDK and initialize it
import { RudderAnalytics } from '@rudderstack/analytics-js';
// Import your auto-generated RudderTyper client:
import { RudderTyperAnalytics } from './analytics/index';

const rudderAnalytics = new RudderAnalytics();
rudderAnalytics.load(WRITE_KEY, DATA_PLANE_URL, {});

// Pass in your @rudderstack/analytics-js instance to RudderTyper client
RudderTyperAnalytics.setRudderTyperOptions({
  analytics: rudderAnalytics,
});

// Issue your first RudderTyper track call!
RudderTyperAnalytics.orderCompleted({
  orderID: 'ck-f306fe0e-cc21-445a-9caa-08245a9aa52c',
  total: 39.99,
});

Note the following:

  • Remember to replace WRITE_KEY and DATA_PLANE_URL in the above snippet with the write key of your JavaScript source and the data plane URL respectively.
  • Run npx rudder-typer to regenerate your RudderTyper client every time you update your tracking plan.

See the sample application for reference.

RudderStack Node.js SDK

  • Import the the RudderTyper-generated client and start making calls using RudderTyper as shown:
// Import Rudder Node SDK and initialize it
const RudderAnalytics = require('@rudderstack/rudder-sdk-node');

const client = new RudderAnalytics(WRITE_KEY, {
  dataPlaneUrl: DATA_PLANE_URL,
  // More initialization options
});

const RudderTyperAnalytics = require('./analytics/index');
// Pass in your @rudderstack/rudder-sdk-node instance to RudderTyper.
RudderTyperAnalytics.setRudderTyperOptions({
  analytics: client,
});

// Issue your first RudderTyper track call!
RudderTyperAnalytics.orderCompleted({
  orderID: 'ck-f306fe0e-cc21-445a-9caa-08245a9aa52c',
  total: 39.99,
});
