Client generator

AlgoKit TypeScript client generator (algokit-client-generator-ts)

This project generates a type-safe smart contract client in TypeScript for the Algorand Blockchain that wraps the application client in AlgoKit Utils and tailors it to a specific smart contract. It does this by reading an ARC-0032 application spec file and generating a client which exposes methods for each ABI method in the target smart contract, along with helpers to create, update, and delete the application.

Usage

Prerequisites

To be able to consume the generated file you need to include it in a TypeScript project that has (at least) the following package installed:

npm install @algorandfoundation/algokit-utils

Use

The cli can be used to generate a client via the following command.

npx --yes  @algorandfoundation/algokit-client-generator generate -a ./application.json -o ./client.generated.ts

For details on how to use the generated client see the more detailed usage docs

Examples

There are a range of examples that you can look at to see a source smart contract ({contract.py}), the generated client (client.ts) and some tests that demonstrate how you can use the client (client.spec.ts).

Contributing

If you want to contribute to this project the following information will be helpful.

Initial setup

  1. Clone this repository locally
  2. Install pre-requisites:

  3. Install AlgoKit - Link: Ensure you can execute algokit --version.

  4. Bootstrap your local environment; run algokit bootstrap all within this folder, which will:

    • Install Poetry - Link: The minimum required version is 1.2. Ensure you can execute poetry -V and get 1.2+
    • Run poetry install in the root directory, which will set up a .venv folder with a Python virtual environment and also install all Python dependencies
    • Run npm install
  5. Open the project and start debugging / developing via:

  6. VS Code
    1. Open the repository root in VS Code
    2. Install recommended extensions
    3. Run tests via test explorer
  7. IDEA (e.g. PyCharm)
    1. Open the repository root in the IDE
    2. It should automatically detect it's a Poetry project and set up a Python interpreter and virtual environment.
    3. Run tests
  8. Other
    1. Open the repository root in your text editor of choice
    2. Run npm run test

Subsequently

  1. If you update to the latest source code and there are new dependencies you will need to run algokit bootstrap all again
  2. Follow step 3 above

Building examples

In the examples folder there is a series of example contracts along with their generated client. These contracts are built using Beaker.

If you want to make changes to any of the smart contract examples and re-generate the ARC-0032 application.json files then change the corresponding examples/{contract}/{contract}.py file and then run:

poetry run python -m examples

Or in Visual Studio Code you can use the default build task (Ctrl+Shift+B).

Continuous Integration / Continuous Deployment (CI/CD)

This project uses GitHub Actions to define CI/CD workflows, which are located in the .github/workflows folder.

Approval tests

Making any changes to the generated code will result in the approval tests failing. The approval tests work by generating a version of client and outputting it to ./examples/APP_NAME/client.generated.ts then comparing to the approved version ./examples/APP_NAME/client.ts. If you make a change and break the approval tests, you will need to update the approved version by overwriting it with the generated version. You can run npm run update-approvals to update all approved clients in one go.
