subgraph-transpile

Transpile AssemblyScript subgraph handlers to native Rust.

Installation

npm install -g @thyme-labs/subgraph-transpile

Usage

subgraph-transpile <subgraph-dir> [--output <dir>]

• <subgraph-dir> — path to a subgraph project (must contain subgraph.yaml)
• --output <dir> — optional output directory for generated Rust code (defaults to <subgraph-dir>/native)

Example

subgraph-transpile ./my-subgraph --output ./my-subgraph/native

This reads the subgraph manifest, ABI files, GraphQL schema, and AssemblyScript mapping handlers, then generates equivalent Rust code including:

• Entity types (types.rs)
• Event structs (events.rs)
• Handler functions (handlers.rs)
• lib.rs and Cargo.toml

Programmatic Usage

const { main } = require("@thyme-labs/subgraph-transpile");

Development

npm install
npm run build
npm test
