Question 1

Does File Viewer require server-side file conversion?

Accepted Answer

The open-source File Viewer focuses on browser-native preview. It handles format detection, rendering, search, zoom, print, and export in the frontend whenever possible, making it suitable for offline deployment and private enterprise networks.

Question 2

Which frontend integrations are supported?

Accepted Answer

File Viewer provides Vanilla JavaScript, Web Component, Vue 3, Vue 2.7, Vue 2.6, React, React Legacy, Svelte, jQuery, CDN/IIFE, Vite Plugin, and full package integration paths.

Question 3

How should teams choose the light packages, presets, and full packages?

Accepted Answer

Light components assemble lite, office, engineering, or all presets on demand. Since 2.1.30, Full packages include preset-all and stay aligned with their same-version File Viewer-owned static assets.

Question 4

Do Full packages still require manual Worker, WASM, and font copying?

Accepted Answer

In Vite, register @file-viewer/vite-plugin with copyAssets:true and dev/build provide packaged Worker, WASM, font, and vendor assets automatically. Webpack, Vue CLI, and other non-Vite builds run the included file-viewer-copy-assets CLI once.

Question 5

Does web-full require an asset copy command?

Accepted Answer

No. Deploy @file-viewer/web-full/dist intact. It contains the renderers plus File Viewer-owned Workers, WASM, fonts, vendor files, and manifest for preset-all.
