FIDL examples

This is a catalog of FIDL examples intended to demonstrate FIDL concepts through simplified implementations of real software workflows.

Example index

The following examples sequentially demonstrate useful FIDL concepts.

Calculator

The calculator example shows fundamental building blocks for creating your first FIDL protocol.

Key-value store

The key-value store example demonstrates how to build a simple key-value store using FIDL in order to learn about the various data types available in the language.

Canvas

The canvas example demonstrates how to build a simple 2D line-rendering canvas using FIDL in order to learn about commonly used data flow patterns.
