Functions

convertFileSrc

convertFileSrc(filePath: string, protocol?: string): string

Convert a device file path to an URL that can be loaded by the webview. Note that asset: and https://asset.localhost must be added to tauri.security.csp in tauri.conf.json. Example CSP value: "csp": "default-src 'self'; img-src 'self' asset: https://asset.localhost" to use the asset protocol on image sources.

Additionally, asset must be added to tauri.allowlist.protocol in tauri.conf.json and its access scope must be defined on the assetScope array on the same protocol object.

Example

import { appDataDir, join } from '@tauri-apps/api/path';
import { convertFileSrc } from '@tauri-apps/api/tauri';
const appDataDirPath = await appDataDir();
const filePath = await join(appDataDirPath, 'assets/video.mp4');
const assetUrl = convertFileSrc(filePath);

const video = document.getElementById('my-video');
const source = document.createElement('source');
source.type = 'video/mp4';
source.src = assetUrl;
video.appendChild(source);
video.load();
