does it work with bun ?

[sigmaSd]

bun in mentioned in the docs so I thought it would work, but it doesn't seem so

bun 1.1.8 (linux)

a.ts

import Ocr from "npm:@gutenye/ocr-node";
const ocr = await Ocr.create();
const s = performance.now();
const result = await ocr.detect(
"path.png",
);
console.log(`${performance.now() - s}ms`, result);

bun add @gutenye/ocr-node bun i bun a.ts

error: Cannot find module "@techstark/opencv-js" from "/home/mrcool/.bun/install/cache/@gutenye/ocr-common@1.3.0/src/backend/splitIntoLineImages.ts"

Deno gives the same error

[sigmaSd]

This @techstark/opencv-js is not mentioned as a dependency that why it fails, seems like this project relies for now on cloning this repo

Also I think you should document that it requires git-lfs extension, it took me a while to figure out its needed since I never used it before

[gutenye]

Run bun a.ts and I get error: Cannot find module "npm:@gutenye/ocr-node", changed import Ocr from "npm:@gutenye/ocr-node"; to import Ocr from "@gutenye/ocr-node" works for me.

The @techstark/opencv-js dependency is in @gutenye/ocr-node package, somehow bun can't find it. But it works for me.

Also I think you should document that it requires git-lfs extension, it took me a while to figure out its needed since I never used it before

Fixed in https://github.com/gutenye/ocr/commit/12b02bbb9b31ed6ef36b2df69cde72a4c2613db1

I just published a new version 1.3.1, fixed can't find #/common/.. file in bun. Please give it a try. And let me know if you still have problems.

[sigmaSd]

still the same error, the error is telling me that ocr-common 1.4.0 is referencing that package but its not specified in package.json

https://www.npmjs.com/package/@gutenye/ocr-common?activeTab=dependencies

[gutenye]

@sigmaSd can you test if this works by adding the missing deps to the peerDependencies field in ocr-common/package.json?

[sigmaSd]

I can do that later Btw you should be also able to reproduce the problem, I think you just need to run the script outside of the repo (the one you have locally)

[gutenye]

I can't reproduce it. bun install deps in ./node_modules folder, not ~/.bun/install/cache folder.

Anyway I moved the deps back to @gutenye/ocr-comon package here, can you re test it? (1.4.1 version)

For deno, it didn't work for me, caused by another error

deno run --reload a.ts
error: Unable to load node_modules/.deno/js-clipper@1.0.1/node_modules/js-clipper/clipper.js imported from node_modules/.deno/@gutenye+ocr-common@1.4.1/node_modules/@gutenye/ocr-common/build/backend/splitIntoLineImages.js

Caused by:
    invalid utf-8 sequence of 1 bytes from index 165105

[sigmaSd]

This was fixed in deno , you can upgrade with deno upgrade --canary to test it, the fix should be released in the next version (1.44.2)

[sigmaSd]

and just for info, bun still doesn't work in my case Bun v1.1.12 (Linux x64 baseline)

error: Cannot find module "@techstark/opencv-js" from "/home/mrcool/.bun/install/cache/@gutenye/ocr-common@1.4.1/src/backend/splitIntoLineImages.ts"

but honestly I'm only interested in deno, and it does work now so I don't plan to investigate further

[sigmaSd]

I see bun does work but only if I do the following:

• mkdir f
• bun add @gutenye/ocr-node
• bun a.js (with the above code)

What didn't work is these next step :

• mkdir f
• bun a.js (no bun add so no package.json , just rely on bun fetching the dependency automatically)

So maybe the second way is not supported ?

Also I just noticed for deno , doesn't detect anything unfortunately, so I guess its something I'll investigate when I can

[gutenye]

The second way is not supported. Thanks for the further investigation.

[sigmaSd]

@gutenye It works now with deno, tested with deno 1.45.4 ocr-node 1.4.4

no need to create a directory, npm install or any thing , just a single typescript file

import Ocr from "npm:@gutenye/ocr-node@1.4.4";
const ocr = await Ocr.create();
const s = performance.now();
const result = await ocr.detect(
  Deno.args[0],
);
console.log(`${performance.now() - s}ms`, result);

and deno run a.ts image
