Effect VS Vanilla JS APIs

Loop Decoder provides two APIs for the Data Store: Effect and Vanilla JS.

Effect API

The Effect API is the most flexible and powerful one, and it utilizes the Effect TS framework. This API uses:

• Effect’s Layers for dependency injection
• Effect’s Generator functions instead of standard async/await functions

Vanilla JS API

The Vanilla JS API is a simpler alternative to the Effect API, but it still covers the main use cases related to data store. This API is ideal for:

• Projects that don’t need advanced features and want to use some of the Built-in Stores
• Simpler implementations with Promise-based async/await
• Easier integration with existing JavaScript codebases

Note

We recommend using the Effect API for most projects.

Project Examples

• Web Playground - always uses the latest version of Loop Decoder

• Decoder API - template for building your own Decoder API server with Loop Decoder

  • Custom SQL Abi Store
  • Custom SQL Contract Meta Store

Vanilla JS API:
