Functions

networkFirst(request: any): Promise<Response>

Parameters:

• request any

Returns: Promise<Response>

Calls:

• fetch
• request.url.endsWith
• newHeaders.set
• caches.open
• cache.put
• response.clone
• caches.match
• console.warn

Code

async function networkFirst( request ) {

    try {

        let response = await fetch( request );

        if ( request.url.endsWith( 'editor/' ) || request.url.endsWith( 'editor/index.html' ) ) { // copied from coi-serviceworker

            const newHeaders = new Headers( response.headers );
            newHeaders.set( 'Cross-Origin-Embedder-Policy', 'require-corp' );
            newHeaders.set( 'Cross-Origin-Opener-Policy', 'same-origin' );

            response = new Response( response.body, { status: response.status, statusText: response.statusText, headers: newHeaders } );

        }

        if ( request.method === 'GET' ) {

            const cache = await caches.open( cacheName );
            cache.put( request, response.clone() );

        }

        return response;

    } catch {

        const cachedResponse = await caches.match( request );

        if ( cachedResponse === undefined ) {

            console.warn( '[SW] Not cached:', request.url );

        }

        return cachedResponse;

    }
