About this repo

The Scripts AssemblyScript SDK is a library of useful classes and functions that are available for all script extension point authors to use when building their extension point API. Their purpose is to provide a standardized set of models to be shared across extension points. This saves extension point authors time and maintains consistency across different script extension point APIs.

Some examples of the models:

  • Money - A representation of a Shopify Money object with operations such as rounding and calculations.
  • Int, Float, OverflowableInteger - Numeric types support
  • Configuration - A representation of a script's configuration.

The exported models are distributed as part of the @shopify/scripts-sdk-as NPM package.

Unit tests

Update docs

npm run docs:update regenerates the TypeDoc API docs. This generally needs to be done whenever an API or doc comment changes.

Build currencies

npm run build:currencies regenerates the assembly/Money/Currency/Currencies.ts file based on the contents of scripts/currencies/currencies.json. This needs to be done whenever the currencies.json file is updated.


npm run fmt will format all AssemblyScript files according to the Prettier config.

npm run fmt:check will validate all AssemblyScript files are formatted properly according to the Prettier config. This command is useful for CI checks.


npm run lint will run ESLint across the codebase.
