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
Troubleshooting
If you get an error during the setup process, run the following commands to clear your cache and local storage:
npm cache clean --force
rm -r ~/.ruddertyper
If you get a “Your workspace does not have any Tracking Plans” error during the setup, verify that your RudderTyper client is on a stable version (v1.x).
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.

Configuration Reference
RudderTyper stores its configuration in a ruddertyper.yml
file in the root of your repository.
A sample configuration looks like the following:
# RudderStack RudderTyper Configuration Reference (https://github.com/rudderlabs/rudder-typer)
# Just run `npx rudder-typer` to re-generate a client with the latest versions of these events.
scripts:
# You can supply a RudderStack API token using a `scripts.token` command. The output of `script.token` command should be a valid RudderStack API token.
token: source .env; echo $RUDDERTYPER_TOKEN
# You can supply email address linked to your workspace using a `scripts.email` command.The output of `script.email` command should be an email address registered with your workspace.
email: source .env; echo $EMAIL
# You can format any of RudderTyper's auto-generated files using a `scripts.after` command.
# See `Formatting Generated Files` below.
after: ./node_modules/.bin/prettier --write analytics/plan.json
client:
# Which RudderStack SDK you are generating for
# Valid values: analytics.js, analytics-node, analytics-ios, analytics-android.
sdk: analytics.js
# The target language for your RudderTyper client.
# Valid values: javascript, typescript, objective-c, swift, java.
language: typescript
# JavaScript Transpilation Settings

scriptTarget: 'ES5'
# Valid values: 'CommonJS','AMD','UMD','System','ES2015','ESNext'
moduleTarget: 'ESNext'
trackingPlans:
# The RudderStack Tracking Plan that you are generating a client for.
# Provide your workspace slug and Tracking Plan id
# You also need to supply a path to a directory to save your RudderTyper client.
- id: rs_QhWHOgp7xg8wkYxilH3scd2uRID

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
andDATA_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,
});
