leancode_contracts_generator 0.19.1

Dart contracts client generator for a CQRS API.

leancode_contracts_generator

Installation

dart pub add leancode_contracts_generator --dev

If your contracts use Topics additionally install leancode_pipe:

dart pub add leancode_pipe

Add dependencies for generating JSON serialization helpers:

dart pub add json_serializable --dev
dart pub add build_runner --dev

Usage

Ensure that you have .NET SDK installed with version capable of building target contracts project.

The version of .NET generator is controlled using .NET tool manifest (see example), the presence of which is required for .NET generator to be found. If it's missing, one can be created with dotnet tool install dotnet-contracts-generate --create-manifest-if-needed.

First run will take longer due to the need to download external dependencies.

After running the contracts generator, generate the JSON serialization helpers:

dart run build_runner build

First initialize a config file filled with defaults with dart run leancode_contracts_generator init, then generate client contracts code with dart run leancode_contracts_generator.

$ dart run leancode_contracts_generator --help
