Code Generation (Codegen)

The Code Generation (Codegen) feature in Tracking Plans automatically generates language-specific code snippets based on your defined event schemas. This streamlines the instrumentation process by providing accurate code represents the schema definition, including:

• Clear structure of the properties object
• Correct keys
• Examples that represent the correct data type
• Comments that specify whether properties are optional

Access codegen

1. Go to Govern > Tracking Plans.
2. Select the Tracking Plan and click on any event.
3. Click View Codegen.

4. To view the corresponding RudderTyper code, toggle on the Show RudderTyper code setting.

Supported languages

Currently, the Codegen feature only generates snippets for the JavaScript SDK. Support for additional languages is coming soon.

RudderTyper

Generated code snippets are helpful, but the best way to make it easy for instrumenting events correctly is to use RudderTyper in your IDE.

RudderTyper is a linting tool that generates and autocompletes typesafe code from tracking plan schemas.

Example

The following image shows how RudderStack translates the event schema definition into the code snippet:

Some notable observations in this example:

• The value of cart_id is set to a string.
• Properties like position, sku, variant, etc. are followed by // optional, denoting that they are not required.
• The products property is structured as an array with products_placement_id as a nested property (integer)
