npm install @file-viewer/vue2.7-full

Ecosystem Matrix

Every standard component package shares @file-viewer/core as the only common foundation, and no framework component package depends on another framework implementation. Core owns format metadata, source loading, the renderer protocol, events, operation APIs, search, zoom, print, and export. Heavy PDF, Word, PPTX, CAD, Typst, and similar pipelines are assembled explicitly through renderer packages or presets; each framework package owns its local controller, component lifecycle, type exports, and ecosystem-specific interaction layer.

Format Support Matrix

The shared format matrix currently covers 24 preview pipelines and 206 file extensions. Full capability is assembled through renderer packages or presets, while component packages only adapt their own ecosystem without nesting through another framework implementation.

Engineering-Grade On-Demand Renderer Assembly

The quickstart flow is: get the component running first, then make the format boundary explicit. Install the component package for the current ecosystem, then choose @file-viewer/preset-lite, @file-viewer/preset-office, @file-viewer/preset-engineering, or @file-viewer/preset-all. For Webpack, Rspack, Rollup, Umi, classic multi-page apps, and other non-Vite stacks, pass capability explicitly through options.preset or options.renderers. The Vite plugin is an optional convenience layer that removes manual imports and copies offline assets.

npm i @file-viewer/vue2.7-full @file-viewer/preset-office

import officePreset from '@file-viewer/preset-office'

const options = {
  preset: officePreset,
  rendererMode: 'replace'
}

When a product combines Office documents with engineering drawings, keep the same preset field and pass an array:

import officePreset from '@file-viewer/preset-office'
import engineeringPreset from '@file-viewer/preset-engineering'

const options = {
  preset: [officePreset, engineeringPreset],
  rendererMode: 'replace'
}

For exact small cuts, install one renderer and pass it through options.renderers:

import { pdfRenderer } from '@file-viewer/renderer-pdf'

const options = {
  renderers: [pdfRenderer],
  rendererMode: 'replace'
}

Vite projects can add the plugin. It auto-discovers installed presets, injects the virtual module, and copies matching Worker / WASM / font / vendor assets:

npm i -D @file-viewer/vite-plugin

import { fileViewerRenderers } from '@file-viewer/vite-plugin'

export default {
  plugins: [
    fileViewerRenderers({
      copyAssets: true
      // No preset option required: the plugin discovers installed @file-viewer/preset-office.
    })
  ]
}

Heavy users that want the complete official demo capability can switch to the full preset. Non-Vite projects keep options.preset; the Vite config stays the same:

npm i @file-viewer/vue2.7-full @file-viewer/preset-all

Use explicit plugin options only when you need customization:

fileViewerRenderers({
  preset: 'auto',        // keep installed preset auto-discovery while scanning source hints
  scan: true,            // detects fileViewerFormats, data-file-viewer-formats, and accept
  formats: ['pdf'],      // adds exact renderers outside the installed preset
  copyAssets: true,
  chunkStrategy: 'renderer'
})

For strict custom cuts or component-library tests, disable injection and pass the virtual module explicitly:

// vite.config.ts
fileViewerRenderers({ formats: ['pdf'], inject: false, copyAssets: true })

// Application viewer entry
import { configuredFileViewerRenderers } from 'virtual:file-viewer-renderers'

const options = {
  renderers: configuredFileViewerRenderers,
  rendererMode: 'replace'
}

• Vue, React, Svelte, jQuery, and Vanilla JavaScript / Pure Web all receive the same options; each package maps them to native props, hooks, actions, plugins, or mountViewer(...) parameters.
• preset-lite covers text, Markdown, code, images, audio, and video; preset-office covers PDF / Word / Excel / PowerPoint / OFD; preset-engineering covers CAD / 3D / drawing / XMind / Geo / Typst / EDA / Data.
• For the smallest custom bundle, skip presets, install individual renderers such as @file-viewer/renderer-pdf or @file-viewer/renderer-word, and pass them through options.renderers.
• fileViewerRenderers() or fileViewerRenderers({ copyAssets:true }) auto-discovers installed presets without explicit configuration. When scan:true is also enabled, use preset:'auto' or autoPresets:true to keep preset auto-discovery.
• scan:true detects fileViewerFormats, data-file-viewer-formats, and upload accept hints so development and production builds select matching renderers automatically.
• copyAssets:true copies PDF/CAD/Typst/Archive/Data workers, WASM, and vendor assets for offline and enterprise intranet deployment.
• builtinRenderers remains available for advanced baseline control or historical compatibility. Normal quick starts only need preset / renderers plus rendererMode.
• If a file is in the supported matrix but its renderer is not assembled, the viewer shows the recommended preset / renderer package. Truly unknown extensions still show an unsupported-format state.
• @file-viewer/preset-all is the full one-step capability path for demos, admin tools, and enterprise all-format workbenches. Normal product surfaces should still prefer narrower presets.

Shared Options And Events

Every ecosystem package uses the same ViewerMountOptions and FileViewerOptions semantics, mapped to framework-native props, events, refs, actions, or plugin APIs.

Option	Description
url	Remote file URL from object storage, business APIs, or intranet file services.
file	File, Blob, or ArrayBuffer for uploads, local selection, or already-fetched binary data.
buffer	Direct ArrayBuffer input after custom download, authorization, or decryption.
name / filename	Display name and extension hint. Pass it explicitly when the URL has no useful extension.
type	Explicit extension or MIME hint that overrides automatic detection.
size	File size hint used in lifecycle context, loading states, and safety limits.
options	The shared FileViewerOptions surface. Every component package keeps the same semantics.
onEvent / onStateChange	Unified event and state subscriptions for imperative wrappers such as Vanilla JavaScript / Pure Web, React, and Svelte. Vue maps the same events to native emits.

Actual Component Props

The table below lists the real props, event channel, and customization entry for every standard package. If you need imperative mount fields such as buffer, name, type, or size, prefer Vanilla JavaScript / Pure Web, React, Svelte, jQuery, or Vue 2. The Vue 3 declarative component intentionally keeps the compact url / file / options entry; wrap raw binary input as a named File when extension detection matters.

Component	Actual props / entry	Event channel	Customization entry
Vanilla JS / Pure Web @file-viewer/web	<flyfish-file-viewer> attributes: src/url, filename/name, type, size, theme, toolbar, toolbar-position, watermark, search, options; also supports mountViewer(...)	viewer-ready, viewer-event, viewer-state-change, viewer-error, onEvent, onStateChange, controller.subscribe()	The Custom Element instance exposes the full controller handle; the IIFE script auto-registers it while keeping imperative mountViewer and the asset copy CLI.
Vue 3 @file-viewer/vue3	url, file, options	load-start, load-complete, unload-start, unload-complete, operation-before, operation-cancel, operation-availability-change, search-change, location-change, zoom-change	Template refs expose FileViewerExpose. For Blob / ArrayBuffer, prefer wrapping it as a named File so extension detection stays deterministic.
Vue 2.7 @file-viewer/vue2.7	url, file, buffer, name, filename, type, size, options, containerClass, containerStyle	viewer-event / viewerEvent	The component instance exposes the full controller handle. This is the Vue 2.7 line behind the historical @flyfish-group/file-viewer package.
Vue 2.6 @file-viewer/vue2.6	Same as Vue 2.7	viewer-event / viewerEvent	Separate Vue 2.6 build for long-lived applications that cannot move to Vue 2.7.
React @file-viewer/react	ViewerMountOptions plus native div props such as className, style, data-*, and aria-*	onEvent, onStateChange	ref exposes FileViewerHandle; useFileViewer() returns ref, props, state, and handle for custom toolbars.
React Legacy @file-viewer/react-legacy	Same as the React package	onEvent, onStateChange	Targets React 16.8 / 17 with a legacy-friendly component export.
jQuery @file-viewer/jquery	$(el).fileViewer(ViewerMountOptions & { replace?: boolean })	onEvent, onStateChange, or getFileViewerController(el).subscribe()	Plugin methods include zoomIn, printRenderedHtml, and searchDocument; replace:false updates the same node in place.
Svelte @file-viewer/svelte	ViewerMountOptions plus className and containerStyle	on:viewerEvent, onEvent, onStateChange	bind:this exposes the controller handle; the use:fileViewer action is also available and adds replace.

Options Field	Description
theme	light, dark, or system. This takes precedence over browser prefers-color-scheme.
watermark	Text or image watermark with opacity, rotation, gap, size, font, and color controls.
toolbar	Controls download, print, HTML export, zoom, toolbar position, and operation-level preflight checks.
search	Document search, highlight class names, case sensitivity, whole-word matching, max matches, and debounce.
ai	Text collection, chunk size, and max text length for provenance, location, vectorization, and external AI workflows.
archive	Archive Worker/WASM URLs, timeout, cache, archive limits, and nested entry preview limits.
pdf	PDF.js worker, navigation pane, outline, thumbnails, rotation, streaming, range chunk size, and credentials.
docx / spreadsheet	DOCX is provided by @file-viewer/renderer-word and uses the self-maintained @file-viewer/docx engine with automatic worker/main-thread selection, continuous flow reading, and async rendering by default; visual pagination is opt-in. Spreadsheet is provided by @file-viewer/renderer-spreadsheet with fidelity-first main-thread parsing, opt-in Worker loading, and opt-in header drag column resizing.
typst / data / cad	Typst, SQLite, CAD/DWG/DXF/DWF WASM, worker, encoding, and rendering strategy options.
hooks / beforeOperation	Shared lifecycle hooks and operation preflight checks for audit, permission, telemetry, and safety controls.

Toolbar Customization

Config	Description
toolbar: false	Hides the built-in toolbar without disabling controller APIs such as download, print, export, and zoom. Use this for a fully custom business toolbar.
toolbar: true	Uses the default built-in toolbar. Download, print, HTML export, and zoom buttons are still shown only when the active renderer supports them.
download / print / exportHtml / zoom	Expresses whether the host allows a button. Final availability is still computed from file type, render readiness, export adapter, and zoom provider state.
position	auto, top, or bottom-right. The default auto floats PDF actions at bottom right to avoid conflicting with the PDF page / outline toolbar.
beforeOperation	Toolbar-level preflight that runs after options.beforeOperation. Returning false or throwing cancels the operation.
beforeDownload / beforePrint / beforeExportHtml	Operation-specific preflight for download permission, print audit, export confirmation, and similar business rules.

For fully custom toolbars, hide the built-in toolbar and call the standard ref / controller APIs from your own UI. Do not implement zoom with an outer CSS transform: scale(); PDF, Excel, CAD, canvas-based, and text-layer renderers should use their internal zoom providers to keep coordinates correct.

Ecosystem	Recommended pattern
Vanilla JS / Pure Web	Use <flyfish-file-viewer toolbar="false"> or mountViewer(container, { options:{ toolbar:false }, onStateChange }); custom DOM buttons can call zoomIn(), printRenderedHtml(), searchDocument(), and other element / controller methods directly. Use viewer-state-change or controller.subscribe() for advanced state sync.
Vue 3	Pass :options="{ toolbar: false }", call downloadOriginalFile(), printRenderedHtml(), exportRenderedHtml(), zoomIn(), zoomOut(), and resetZoom() through the template ref, and sync buttons with @operation-availability-change plus @zoom-change.
Vue 2.7 / 2.6	Use toolbar:false, call instance methods through $refs.viewer, and listen to @viewer-event for operation-availability-change or zoom-change.
React / React Legacy	Prefer useFileViewer({ options:{ toolbar:false } }); pass viewer.props to the component, bind custom buttons to viewer.handle, and read viewer.state.availability / viewer.state.zoom.
jQuery	Use $("#viewer").fileViewer({ options:{ toolbar:false } }); buttons can call $("#viewer").fileViewer("zoomIn") or read capability state through getFileViewerController($("#viewer")).subscribe().
Svelte	Use <FileViewer bind:this={viewer} options={{ toolbar:false }} />; buttons call viewer.zoomIn() / viewer.printRenderedHtml(), with on:viewerEvent or onStateChange for state sync.

Lifecycle And Operation Events

Event / hook	Description
load-start / hooks.onLoadStart	Fires when parsing or downloading starts. Context includes filename, type, source, version, URL, File, and size.
load-complete / hooks.onLoadComplete	Fires when the current document has rendered. Context includes duration, source data, and version.
unload-start / hooks.onUnloadStart	Fires before replace, reset, or component unmount so external state or resources can be saved.
unload-complete / hooks.onUnloadComplete	Fires after the previous document is released. The reason is replace, reset, or component-unmount.
operation-before / operation-cancel	Fires around download, print, HTML export, and zoom actions. Returning false from beforeOperation cancels the action.
operation-availability-change	Fires when download, print, HTML export, or zoom support changes for the active format.
search-change / location-change / zoom-change	Fires when search matches, document anchors, or zoom state changes so host UIs can stay in sync.

Public Operation API

API	Description
load / update / reload / destroy	Imperatively load, update, reload, and destroy the viewer.
downloadOriginalFile()	Downloads the original file while respecting toolbar and beforeOperation checks.
printRenderedHtml()	Prints the complete rendered document using the best available per-format print adapter.
exportRenderedHtml()	Exports rendered HTML for archiving, audit, or offline review.
zoomIn() / zoomOut() / resetZoom()	Uses the active renderer zoom provider instead of outer CSS transforms that can break coordinates.
searchDocument() / nextSearchResult() / previousSearchResult()	Runs document-level search and navigates highlighted matches.
collectDocumentAnchors() / scrollToAnchor() / scrollToLine()	Collects pages, outline items, headings, or code-line anchors and scrolls to them.
getDocumentTextChunks()	Returns structured text chunks for search, AI provenance, vectorization, and external indexes.
getOperationAvailability() / getZoomState() / getSearchState()	Reads current capability, zoom, and search state for custom toolbars.

Workers, WASM, And Private Deployment

Asset	Description
Shared viewer assets	The Pure Web package ships file-viewer-copy-assets to copy workers, WASM, vendor files, and examples into your static directory.
CAD / DWG / DXF / DWF	Configure options.cad.wasmPath, workerUrl, dwfWasmUrl, and dxfEncoding for self-hosted or intranet deployment.
PDF / DOCX / Excel	Configure options.pdf.workerUrl, options.pdf.cMapUrl, options.pdf.wasmUrl, options.pdf.standardFontDataUrl, options.docx.workerUrl, options.docx.workerJsZipUrl, and options.spreadsheet.workerUrl; PDF probes the real static worker first and lazy-loads the packaged handler when unavailable; DOCX chooses worker or main-thread parsing automatically, Electron file:// and other unsafe local protocols fall back without user configuration, Excel Worker remains explicit opt-in, and header drag column resizing is controlled by options.spreadsheet.resizableColumns.
Typst / SQLite / Archive	Configure Typst compiler/renderer WASM, data.sqlWasmUrl, and archive.workerUrl / archive.wasmUrl as needed; Typst renders through local WASM only and never falls back to a public CDN.
Drawing	Draw.io uses the official diagrams.net offline viewer shipped with viewer assets by default; override options.drawing.viewerScriptUrl for custom paths, or set preferOfficial:false for the built-in SVG fallback.
Offline deployment	Runtime preview code does not depend on public CDN or third-party online assets; file-viewer-copy-assets copies PDF, CAD, Typst, SQLite, archive, Draw.io, DOCX worker/JSZip, and Office worker/vendor assets.
Deployment principle	Heavy workers, WASM files, and parser libraries stay lazy-loaded and are only requested when the active file type needs them.

Quality Gates

• Component packages only depend on @file-viewer/core and their own ecosystem dependencies. They do not nest through another framework component package.
• Format parsing, search, zoom, print, export, watermark, lifecycle, and beforeOperation semantics all come from the same core.
• Releases should pass type checks, component API verification, README generation checks, format-matrix verification, standalone repository export, and browser smoke tests.

See the official documentation for options, lifecycle hooks, beforeOperation, theme, watermark, search, zoom, print, and export APIs: https://doc.file-viewer.app/
