This is the forked version of PDF.js. NOT the official repo.
If you are looking for the official repo of PDF.js, please visit mozilla/pdf.js.
We publish the distribution files (the viewer) as private npm packages.
Using npm install with NPM v7 above will upgrade the lockfileVersion of package-lock.json and result in a huge package-lock.json file.
You can use npm ci instead to install the dependencies: https://docs.npmjs.com/cli/v7/commands/npm-ci
There are several scripts to build the viewer with different setting:
npm run build:generic # For modern browser (Not include iOS Safari)
npm run build:generic-legacy # Support more browsers
npm run build:minified # For modern browser (Not include iOS Safari) and with JS minified
npm run build:minified-legacy # Support more browsers with JS minifiednpm run build will run npm run build:minified-legacy by default.
