vue-pdf-optimization
PDF.js is very advanced JS library for parsing and displaying PDF files by Mozilla. This project aims to provide simple and lightweight Vue.js component, that downloads library files lazily from cdn with minimal setup.
Similar projects:
- vue-pdf - includes PDF.js files into your bundle with webpack. Sometimes this may be undesirable because:
- it may require additional webpack configuration
- webpack processing can lead to issues
- latest webpack has a bug in development mode with worker files
- it will increase bundle size (pdf.js viewer + worker = about 800 kb) and build time.
Install
yarn add vue-pdf-optimization
