Set up the Development Environment
Setting up the environment for AssemblyScript smart contracts is relatively simple. All you need to install are nodejs and ipyeos, just like developing a webpage using react or vue.js. You can download and install nodejs from the link below:
https://nodejs.org/
Next, install ipyeos, which is a python package:
python3 -m pip install -U ipyeos
If your platform is Windows or MacOSX M1/M2, you also need to download an image that includes the ipyeos tool:
docker pull ghcr.io/uuosio/ipyeos:latest
The recommended software for installing and running Docker on macOS is OrbStack. For other platforms, you can use Docker Desktop.
Test the Development Environment
You can test if your development environment is set up successfully in the following way:
First, download the sample code from the link below:
https://github.com/uuosio/as-template
Then, use the cd command to enter the directory and run the following command to compile:
cd as-template
yarn
yarn build
If two files counter.wasm and counter.abi are generated in the assembly/target directory, it means the compilation was successful.
Next, run the following command to run the Python test script for testing:
yarn pytest
You will see the following output:
[(hello,inc)->hello]: CONSOLE OUTPUT BEGIN =====================
++++++++count:1
[(hello,inc)->hello]: CONSOLE OUTPUT END =====================
[(hello,inc)->hello]: CONSOLE OUTPUT BEGIN =====================
++++++++count:2
[(hello,inc)->hello]: CONSOLE OUTPUT END =====================
Additionally, you can also use typescript to write test scripts. The test code is in the tests/test.spec.ts file.
Before testing, you need to run the eosdebugger tool in ipyeos in the terminal:
eosdebugger
When you see an output similar to the following:
2023-05-30 16:03:21,259 INFO wasyncore 486 Serving on http://127.0.0.1:9093
It indicates successful operation.
Then use the following command to run the test:
yarn test
You will see the same output in eosdebugger.
