Instalo pdfjs-lib en el proyecto angular para convertir PDF a lienzo después de recibir este mensaje de error:

 Error: ./node_modules/pdfjs-dist/build/pdf.js 2094:26 Module parse failed: Unexpected token (2094:26) File was processed with these loaders: * ./node_modules/@angular-devkit/build-angular/src/babel/webpack-loader.js * ./node_modules/@ngtools/webpack/src/ivy/index.js You may need an additional loader to handle the result of these loaders. | async destroy() { | this.destroyed = true; > await this._transport?.destroy(); | this._transport = null; |

el objetivo es convertir la página PDF en lienzo antes de renderizar en HTML:

 import * as pdfjslib from 'pdfjs-dist'; pdfjslib.getDocument(url).promise.then(async(pdf) => { pdf.getPage(1).then(async (page) => { let viewport = page.getViewport({ scale: 0.3 }); let canvas =<HTMLCanvasElement> document.getElementById("card"+pageId); let context =<CanvasRenderingContext2D> canvas.getContext("2d"); canvas.width = viewport.width; canvas.height = viewport.height; await page.render({ canvasContext: context, viewport: viewport }); resolve("ok"); }).catch((err) => { reject("Erreur sur le pdf!!"); }); }).catch((err) => { reject("Erreur sur le pdf!!"); });
