expo-pdf-reader

A wrapper around Xavier Carpentier's rn-pdf-reader-js that gracefully degrades in the web

Simply import PDFReader from '@zachlove/expo-pdf-reader' instead of 'rn-pdf-reader-js'. In the web, the component gracefully degrades to an object that uses the browser built-in PDF viewer if available. While much more limited, this allows Expo to preview the app in a browser without errors.

This is for development purposes only. Projects that need a proper PDF viewer for the web should use better solutions like React-PDF instead.

Install

With npm:

npm install @zachlove/expo-pdf-reader

With yarn:

yarn add @zachlove/expo-pdf-reader

With expo:

expo install @zachlove/expo-pdf-reader

If using Expo, add the module to webpack.config.js:

const createExpoWebpackConfigAsync = require('@expo/webpack-config');

module.exports = async function (env, argv) {
    const config = await createExpoWebpackConfigAsync({
        ...env,
        babel: {
            dangerouslyAddModulePathsToTranspile: [
                '@zachlove/expo-pdf-reader',
            ],
        },
    }, argv);
    return config;
};

If webpack.config.js does not exist, create it with:

expo customize:web

import React from 'react';
