Safety measures (statically, not runtime) for libraries that require environment variables?

Suppose I have a Deno library which expects certain environment variables to have been configured, otherwise a crash will happen. Does anyone know of a good way to somehow ensure at "compile-time" that whatever Deno application is using the library has configured these environment variables?

I have TWO Deno project with and cannot use the debugger with ONE of them. One project debugs fine, the other does not. I do not know where to start to mitigate the problem. I see this problem with VS Code fronting the debugger and by using chrome://inspect directly. First, the error message:...

VSCode "quick fix" for missing import doesn't use import map

When adding a missing import via option + Enter, it will suggest the full URL, despite that URL being in my import map. After accepting the suggestion, it'll suggest to change the import to use the value in the import map instead. Can this be configured to be one operation instead of two?

Testing my Oak `Application` end-to-end

I have an Oak application, and I'd like to test the main const app = new Application() configuration, making sure e.g. that all the routes are being found, etc. I've only been able to find createMockContext, etc., but I can't figure out how to make a "mock server request" that would be accepted by Application.handle basically?...

Adding methods to Oak's Context?

I am trying to figure out how to configure my Oak application/router so that my routes can do things like ctx.customMethod(), could someone point me in the right direction? I can only really find how to customize the State, but that would only let me do ctx.state.customMethod() – is that how you're supposed to do it instead of what I had in mind?

Custom JSX transform from local module

Is it possible to define a JSX transform within the same codebase? All of the examples show referencing it from a remote module like https:/esm.sh/preact I've tried this, but it is unable to load my local jsx-runtime module because it doesn't recognize it as bing JS or TS. https://github.com/cowboyd/deno-jsx...

some programming language guides like the rust book lets you directly edit and run code in their docs, would it be possible for deno to do this in client-side? i'm planning to create a blog in deno and being able to run code snippets inside posts would be helpful. https://doc.rust-lang.org/book/ch01-02-hello-world.html...
