Deno Kv: "Database is locked" on enqueue
Apparently this happens when multiple processes try access the
kv db file at the same time. I'm not sure how to prevent it as of yet. For now I've gotten around it by implementing a retry mechanism for the enqueue call, it just attempts to enqueue in a try catch within a for loop a couple times. I haven't run into a case where it fails to enqueue more than once so this seems to be fine for what I need for now.3 replies
Different behaviour between Node and Deno with npm package
update: I dove into the lib code which was quite heavily reliant on the
isomorphic-ws npm package(more specifically the ws package). I created a replica replacing all the websocket code with the equivalents from the following deno package: https://deno.land/x/websocket@v0.1.4. This seems to work 🙂2 replies
Relative import path "oak/router" not prefixed with / or ./ or ../ and not in import map
thanks for your reply. I had added that import map as part of a few initial attempts to get around this issue, and interestingly it does work using that, combined with my workaround mentioned above. Subsequently though I have removed it and tested removing some of my explicit imports from
deno.json, which to my surprise has started working. So essentially my project is back in the state that it was when I first ran into this issue(at least I think it is) however it is now working. maybe something is fixed now or of course I could have been mistaken all along 🙂 thanks5 replies
Relative import path "oak/router" not prefixed with / or ./ or ../ and not in import map
I have figured out that explicitly adding the sub paths of the imports to my
deno.json file seems to solve the issue, for example:
if I want to use oak/router in main.ts, I have to add "oak/router": "jsr:@oak/oak@17.0.0/router", to deno.json(ontop of the already existing oak import). This is weird, because locally I can just have the top level oak import and deno automatically resolves jsr:@oak/oak@17.0.0/router when I specify oak/router. I wonder why this is different when deploying, perhaps something to do with deployctl?5 replies
Site runs fine but vscode is filled with errors.
I've had similar things. Adding
"deno.importMap": "deno.json" to .vscode/settings.json, with a window reload, solved a lot of these kinds of issues for me. Sometimes the editor does seem to get stuck though where everything is red, usually a window reload works as well.8 replies
Fresh pattern help
100%. Would need to persist it somehow in the island the first time the page loads. The cookie route seems cleaner in this case. Although I am trying to get my head around the possibilities because this is quite a common use case if I'm not mistaken. Submit form -> load new page with data from the the form.
