Can I use hono with JavaScript (not TypeScript)
Hi, I have a very small API project that I'm deploying on cloudflare workers, and was wondering if I can just switch to javascript instead of typescript?
I tried searching the docs but can't find anything (possibly skill issues). Apparently JS works, it just shows me all the compiler warnings, but I still want to switch nonetheless. I am aware of the benefits of TS, but need JS for my project specifically.
Thank you, and sorry if this has already been answered!

js is fine
Thank you
np
typescript is (mostly) just javascript with annotations
the typescript bit is never executed at runtime
enums complicate this a bit, but i don't think hono uses those, and they'd be transpiled down to js anyways
Ok, so I'll just turn off compiler warnings and continue with JS
like back in the old days
Even if you don't want to write in TS files, you will benefit from having TS enabled in your project
It can still lint and such
Typescript also understands jsdoc
Just add the
noEmit flag to your compiler optionsGreat, thanks! Yup I'd like to use JSDoc for this project, it's kinda my goal.
jsdoc is limited, what I usually end up doing when I want js files, is to add complementary
.d.ts files
Or you can have one .d.ts file with interfaces/types and use it globally with jsdoc
PS: if a .d.td file does not have import/export, it acts like a global definition, so you can use it anywhereWould probably be enugh for my needs. Would like to avoid complicating and push simplicity boundaries instead
I implore you to not define complicated types with jsdoc, but to rely on
.d.ts for that
jsdoc can't do generics and suchI will be moving from the ground up on this one, with no pre-emptive typing, only add types and complicate the codebase if something breaks. The project is confounded to be small so I may get away with it.
If you have import/export you won't get away with it
Even though typescript has the ability to type check code w/o type annotations, it doesn't do that if it is not in a .ts file
It does the bare minimum
jsdoc makes it check more stuff
But wherever you don't use it, you won't have types
does this not work? https://www.typescriptlang.org/tsconfig/#checkJs
From my experience it doesn't, but I'll give it the benefit of the doubt because I used it on a large project that had no types
i'm a little confused. using typescript with jsdocs instead of
.ts annotations is still typescript/will still give you typing
svelte uses jsdocs internally for their typingThey won't use jsdoc where they think it's not needed is what they meant
At least that's what I gathered
@ThinkValue so do you want typing w/o the
.ts, or are you trying to avoid types altogether?Avoid types, use JSDoc where needed
I think the answers above are more than good enough to solve my problem.
this seems contradictory. it sounds like you're trying to avoid explicit typing, rather than typing altogether. once you're "in" the typescript ecosystem, you're in. either your code will be type-checked or not
just something to keep in mind
Since I can't (or don't know how to) use a .js file in hono, .ts will have to do. But I'll turn off the checking. At the end of the project, will add JSDoc if needed.
Sorry for the photo
For simple types you may think you can get away with this
But you'll be wrong

Can I get away with math?
It's a small Json in, Json out calculation API
with math? what do you mean?
All I'm doing is pulling some data, making calculations and returning JSON
The link above is my work in progress output. No types or JSDoc atm
gotcha. could get a little messy constructing object types in jsdocs (rather than in a
d.ts, but if you've only got a few properties per object, @Arjix's @typedef suggestion will work fine
