Download clientside file

I have created a demo of FileSaver. First off, you want to instantiate a BlobBuilder. Not saving textual data? The following is an example of setting generating some binary data and saving it.

If you're generating large files, you can implement an abort button that aborts the FileSaver.

AFAIK there is no way with only js. It seems nobody here has provided an automatic client side cross-browser solution so here it is: stackoverflow.

Davide - I just show the way to increase his knowledge that we can do it in ie browser , and my answer some how meet with his half requirement..

I see your point but wanted to note we should not target any specific browser or operating system, code above would probably fail on ipad or any other non windows platform.

When it intercepts a request, it can do anything you wish to it see use case ideas , but the classic example is saving the network responses offline and then providing those in response to a request instead of the responses from the network.

In effect, it allows you to make a web site work completely offline. The Cache API is another client-side storage mechanism, with a bit of a difference — it is designed to save HTTP responses, and so works very well with service workers.

Let's look at an example, to give you a bit of an idea of what this might look like. We have created another version of the video store example we saw in the previous section — this functions identically, except that it also saves the HTML, CSS, and JavaScript in the Cache API via a service worker, allowing the example to run offline! See IndexedDB video store with service worker running live , and also see the source code.

The first thing to note is that there's an extra bit of code placed in the main JavaScript file see index. First we do a feature detection test to see if the serviceWorker member is available in the Navigator object. If this returns true, then we know that at least the basics of service workers are supported.

Inside here we use the ServiceWorkerContainer. When its promise fulfills, the service worker is deemed registered. Note: The given path to the sw. If you wanted to host this example on your own server, you'd have to change this accordingly. This is rather confusing, but it has to work this way for security reasons. The next time any page under the service worker's control is accessed e.

When this occurs, an install event is fired against the service worker; you can write code inside the service worker itself that will respond to the installation. Let's look at an example, in the sw. You'll see that the install listener is registered against self.

This self keyword is a way to refer to the global scope of the service worker from inside the service worker file. Inside the install handler we use the ExtendableEvent. Here is where we see the Cache API in action. We use the CacheStorage. This promise fulfills with a Cache object representing the video-store cache. We then use the Cache.

With the service worker registered and installed against our HTML page, and the relevant assets all added to our cache, we are nearly ready to go. There is only one more thing to do, write some code to respond to further network requests.

This is what the second bit of code in sw. We add another listener to the service worker global scope, which runs the handler function when the fetch event is raised. This happens whenever the browser makes a request for an asset in the directory the service worker is registered against.

Inside the handler we first log the URL of the requested asset. We then provide a custom response to the request, using the FetchEvent. Inside this block we use CacheStorage. This promise fulfills with the matching response if a match is found, or undefined if it isn't.

If a match is found, we return it as the custom response. Safari 9. Example for React projects. Type declarations.
