The API is mature enough for me to introduce <a href="https://jsonapi.org/format/#fetching-filtering">filtering</a> via the <a href="https://jsonapi.org/recommendations/#filtering">Filter</a> query parameter used in JSON:API.</p> <p>I would like to support dynamic filtering, I want to avoid creating nested if-else/switch statements that check if a given input is part of the filter criteria, and if it is then it gets appended to a filtering clause. For example, take the following API request, it uses the <a href="https://docs.oasis-open.org/odata/odata/v4.01/odata-v4.01-part2-url-conventions.html#_Toc31361038">OData</a> filter syntax.</p>
