PDFix SDK Wasm example Angular

Example project demonstrating how to use PDFix SDK WebAssembly build in Angular. The PDFix SDK Wasm is implemented in this Angular project using a Web Worker. Web Workers are a simple means for web content to run scripts in background threads. The worker thread can perform tasks without interfering with the user interface. See "Using Web Workers"

Prerequisites

All platforms

Node.js: Download and follow installation instructions: https://nodejs.org/en/download/
Angular CLI: npm install -g @angular/cli

Download

Clone the repository:
git clone https://github.com/pdfix/pdfix_sdk_example_angular.git

Run the example

Run ./pdfix-sdk-example-angular/configure.sh to get the latest PDFix Wasm package and to install dependent npm packages
Serve the Angular project: ng serve
Navigate to http://localhost:4200/ or serve with --open flag: ng serve --open

Example description

From a rough point of view, the example demonstrates the page rendering of a sample PDF document. Upon opening the served Angular App the PDFix SDK Wasm is loaded in the background thread - the Web Worker, then a sample PDF document is opened, the document pages information is retrieved and when ready, the first document page is rendered with options to render other pages.
