QUESTION
I'm working with an application that uses Tesseract (OCR) to read text from images.
I would like to take some JS files from node_modules/tesseract.js/dist and make them downloadable in the browser.
I know I can just copy the files to ./public and next.js will serve it statically from there, but then if I update my version of Tesseract, I may need to update those files as well. So maintenance becomes a problem.
My 1st thought is to customize my webpack config to copy the files from node_modules/tesseract.js/dist to ./public/tesseract (or something like that). That would make sure the files get re-copied if I update Tesseract. But I'm not particularly savvy with webpack and haven't figured out how to do that yet.
My 2nd thought was to "proxy" the retrieval of the JS file's content and just make the content available as a "page" in next.js (but this seems super hacktastic).
I feel like this is something that shouldn't be so complicated ... but I've not been able to figure it out myself yet.
Thanks in advance!

Answered 2022-Apr-15 at 18:54Yup agreed, updating your server to serve a node_modules
path sounds a bit dangerous.
I personally would just copy over these files with webpack like you mentioned.
Here are the docs on Next.js on how to set up a custom webpack config.

I use tesseract.js for detecting numbers in Node JS. For example this is my image :
I run my script and it detects something like this:
289 ,0
And due to noises in the image, it considers space, other signs like comma and etc.
Is there anyway I can specify just numbers and no others signs like space and commas?

i'm facing the following error after install ADMOB PLUS, how to fix it? it's showing Blank page:
...ANSWER
Answered 2020-Sep-02 at 15:46SOLUTION:
It appears because it's giving you the error all the time, I'm using the "Cordova installation" (Didn't work the ionic wrap or capacitor way). "Google ad test" works perfectly on a device, I read that after the app published on "Google play store", the ads will work (Admob Plus)
Install cordova admob plus:
cordova plugin add cordova-admob-plus --variable APP_ID_ANDROID=YOUR_APP~ID
Full example on app.component.ts
import { Component } from '@angular/core'; import { Platform } from '@ionic/angular'; import { SplashScreen } from '@ionic-native/splash-screen/ngx'; import { StatusBar } from '@ionic-native/status-bar/ngx';
declare var admob;
@Component({ selector: 'app-root', templateUrl: 'app.component.html', styleUrls: ['app.component.scss'] }) export class AppComponent {
constructor( private platform: Platform, private splashScreen: SplashScreen, private statusBar: StatusBar ) { this.initializeApp(); }
initializeApp() { this.platform.ready().then(() => { this.statusBar.styleDefault(); this.splashScreen.hide(); this.addAdMob() }); }
addAdMob() { //admob.setDevMode(true) admob.interstitial.load({ id: { android: 'YOUR_ANDROID_ID', ios: 'test', }, }).then(() => admob.interstitial.show()) } }
