Earlier quoted context omitted.

fastn is an ingredient to kulfi project. fastn.com is a full stack programming language we (FifthTry, Inc, the company behind these) have built, and it is the web server that is going to be part of Kulfi app. The comparison posts, TODO, copyright etc we will do/fix when we get around to it. It's all open source, you can send PRs as well.

How does fastn handle errors? Is is possible to perform the SQL query client side or does it prevent / add friction for such? Can I visit `/foo/";DROP%20TABLE%20users;/` or does it handle inputs properly?

So you can write SQL queries[1] in fastn documents, create dynamic urls[2], get request data[3], or write backend in wasm[4].

The input to sql queries are passed using bind parameters[5], so it should not have SQL injection issue.

FifthTry.com is built using fastn. You can checkout source code if lets-update[6] to see some open source fastn code.
