Usage

1. Request a 30-day FREE trial license here for different SDKs, and then update the license keys in the app.js file.

   // Dynamic Web TWAIN
   let parameters = {
       license: "LICENSE-KEY",
   };
   
   // Dynamsoft Barcode Reader
   barcode4nodejs.initLicense(
       "LICENSE-KEY",
   );
   
   // Dynamsoft Label Recognizer
   mrz4nodejs.initLicense(
       "LICENSE-KEY",
   );
   
   // Dynamsoft Document Normalizer
   docrectifier4nodejs.initLicense(
       "LICENSE-KEY",
   );

2. Install Dynamsoft service for Dynamic Web TWAIN:

   • Windows: Dynamsoft-Service-Setup.msi
   • macOS: Dynamsoft-Service-Setup.pkg
   • Linux:
     • Dynamsoft-Service-Setup.deb
     • Dynamsoft-Service-Setup-arm64.deb
     • Dynamsoft-Service-Setup-mips64el.deb
