Example Go server with concurrency

What does it do?

After calling endpoint /v1/api/smart with timeout parameter, server will make GET request to URL defined in environment variables (.env). (TBD) If server will not respond within 300 milliseconds, another 2 requests are fired concurrently. Endpoint will return the first successful response (including the first one). If there is no successful response, endpoint will return error. If there is no response from any of requests, endpoint will return error.

## How to run it?

make start

OR

make restart

Docker must be running!

By default, server will run locally on http://127.0.0.1:4001/. Only one endpoint is defined: /v1/api/smart with query param timeout. Timeout can only be numeric value, otherwise BAD REQUEST is returned.

Pre-commit

• Pre-commit needs to be installed on your machine (https://pre-commit.com/)
• run pre-commit autoupdate and pre-commit install
• pre-commit hooks are automatically installed from .pre-commit-config.yaml file

Pre-commit config dependencies

You need to install following dependencies manually:

• golangci-lint https://golangci-lint.run/usage/install/#local-installation

Performance testing

Run make test - this command will create a batch of 10 * 100 concurrent request (1.000 in total). At the end, you will see the performance.
