Understand
What Mero DevTools is, the two CLIs it ships, and how the codegen pipeline turns an ABI manifest into TypeScript. Start here →
Mero DevTools
Two command-line tools for building Calimero apps in TypeScript. abi-codegen turns a WASM-ABI v1 manifest into a fully-typed client class; create-mero-app scaffolds a new project from a starter template. No hand-written RPC glue.
Generate a client
Point calimero-abi-codegen at an abi.json and get a typed client class
with one method per contract method. CLI reference →
Use the API
Drive the parser and generator programmatically from your own build tooling or Vite/Rollup plugin. Programmatic API →
ABI format
The WASM-ABI v1 manifest: types, methods, events, intent, and migrations — the JSON the generator reads. Read the format →
The generated client targets @calimero-network/mero-react
(the MeroJs runtime). For the protocol these apps run on, see the
Calimero Core docs.
