README
This package demonstrates how we can use web APIs to allow programs to communicate with each other. The code here is illustrative only. I've tried to keep it as simple as possible, and this definitely is not typical of production code. This example also does not include any architecture and only runs locally on your machine.
You can watch me demo this here: https://youtu.be/FnYccT9Q6i4
There are three folders.
- js: JavaScript package with an API to find average of two numbers
- python: Python package with an API to find sum of two numbers
- frontend: A simple UI where the user can request the average of two numbers
The frontend calls the JS API which calls the python API.
How to install and run
Run the following in three separate terminal windows.
cd python
pipenv install
pipenv shell
python main.py # serves the POST /add api on localhost:5000
cd js
yarn install
yarn run start # serves the POST /average api on localhost:3000
cd js
yarn run serve # serves the frontend locally
That's all, folks.
