Construct projects are based on HTML5, which makes them perfectly suited for web publishing. This guide includes some useful information to know when publishing Construct games online.

To publish to web, employ the Web (HTML5) option when exporting. When the consign finishes, you'll go a zip file which contains all the files to upload.

Exported games won't work until you upload them

Games will not work if you lot run them from disk. If you excerpt the exported zip to your computer and double-click index.html to run it, the game volition start using a file:/// URL instead of a http:// or https:// URL, since the game is on disk and not on a server. For security reasons browsers have some tight limitations on what tin be done in a web page from a file:/// URL, and these usually finish Construct games from working. The best workflow is to exam by previewing in Construct during evolution, so immediately publish the game to the spider web after exporting. If you run a game from disk yous might meet a messagebox reminding y'all of this ("exported games won't work until you upload them").

If you actually need your game to run from the desktop, use a desktop export option instead. If you demand to exam on mobile, you lot can employ Remote Preview instead of having to export repeatedly.

Local hosting

Advanced users might desire to consider running a local HTTP server with a server like nginx or Caddy. These are relatively easy to set up upwards to serve the contents of a folder on your computer at a URL similar http://localhost:8080. Then you can but copy the exported project to the server's folder, and load information technology in a browser. The game will work since it is running on a HTTP URL.

Uploading to the web

You lot will need a web server to upload your game to. If you don't have ane, at that place are many services where you lot tin can hire a cheap static file host. The specific steps for uploading files to your server depend on your host. If y'all need help finding out how to do that, contact your host. The procedure sometimes involves tools like FTP, Remote Desktop, or a tool on the host'south website. Alternatively you tin can export to the Scirra Arcade which hosts your game for you.

There are lots of possible services out there you could use. Ane handy one is Netlify Drop, since it provides a really quick manner to go started: elevate and drop in a binder of files for instant hosting.

In one case uploaded, yous should have a link you can share and beginning publicising your game! If you've designed your game with touch on controls it ought to work nicely on mobile browsers as well.

It'south mutual to brand a mistake while uploading your files. If you forget to upload a file or folder, the game could break. If your game does not seem to piece of work one time uploaded, check for browser errors and hopefully there volition be a useful message (e.k. "myfile.png returned 404 not plant", indicating you lot forgot to upload myfile.png).

Setting up MIME types

For all features to piece of work correctly, your web server should have the right MIME types fix up. This is a way for associating file extensions (like .png) with a content type (like paradigm/png). If the server does not know about some file extensions that Construct uses, it can return 404 Not Constitute for the file, or interpret the file incorrectly and corrupt it. For more information see the manual entry on MIME types.

Employ secure hosting

Many Construct features require secure hosting to work. This ways hosting your website on HTTPS (with https:// in the URL), rather than insecure HTTP (with http:// in the URL). For instance offline support, fullscreen, geolocation access, camera/microphone access, and several other features all require HTTPS hosting to work correctly. It is likely in future even more features will require secure hosting.

These days any new server you gear up up should be secure from the start. If you have existing insecure spider web sites, you lot should start updating them to be secure.

If your website is not already secure, contact your host for back up in making sure it is secure. You may need to pay to purchase a document. Alternatively the Allow's Encrypt service allows yous to get certificates free of charge.

Domain lock

If you desire to limit your game to only working on certain websites, yous can simply compare the Browser.Domain expression in the Browser object. For case if you host on https://world wide web.mywebsite.com/mygame/, the Domain expression will be www.mywebsite.com. You lot can make the game refuse to play if this value is not from a website y'all control. (Annotation that preview mode runs on preview.construct.net, and so you should probably allow this domain besides!) This makes it slightly more hard for someone to copy your game. Note this check - whatever whatsoever other kind of bank check you implement - tin still be circumvented. As with many security bug, the goal is mainly to get in more hard to copy, rather than making it completely impossible (which is often infeasible).

Cross-domain requests

If your game loads content from another domain, this is called a cross-domain asking and some security limitations can affect whether the request is allowed. For instance if your game is hosted on mywebsite.com, and tries to load content from otherwebsite.com, the request might be blocked and the load may fail. This can affect AJAX requests, loading images in to objects like Sprite, playing videos, or any other time you lot load content from a URL.

Browsers limit requests according to their domain, scheme, and port. Together these are referred to as an origin. Requests to other origins crave Cross-Origin Resources Sharing (CORS) to be set up, otherwise the browser may be blocked. Typically this involves sending the HTTP header Access-Control-Let-Origin in the response of the server hosting the content. If this header allows the asking, it tin succeed. The requests can be express to certain origins, or you tin can use the post-obit header to let requests from any server:

Admission-Control-Let-Origin: *

Don't exercise this for anything security sensitive (similar profile information) since it allows the content to exist accessed by any website on the Net! However information technology'south usually safe for static files that you merely want to share across domains.

Embedding

If you want to embed a game within another web page, you tin can brandish it using an iframe element. Simply signal the iframe to the web address of your game. For example:

              <iframe src="https://world wide web.mywebsite.com/mygame/" width="600" superlative="400" scrolling="no" noresize="noresize" />

This will create a fixed size iframe (600x400) inside of which the game volition appear. By default the game will automatically scale to fill whatever size the iframe is ready to. However if it'south a fixed size game, brand sure the width and summit attributes of the iframe tag match the viewport size of the game.

The scrolling and noresize attributes are necessary to ensure the iframe displays at the right size on some versions of iOS.

Allowing fullscreen

It's still possible for games inside iframes to switch in to fullscreen mode, where it takes up the entire display. To support this, your game must not be fixed size (Fullscreen way must not be Off). So use the Browser object's Request fullscreen activity in your game.

Finally, you lot must add the allowfullscreen aspect to the iframe tag like this:

                <iframe src="https://www.mywebsite.com/mygame/" allowfullscreen="true" width="600" height="400" scrolling="no" noresize="noresize" />

With all that in identify, your iframed game should now be able to "break out" in to full screen fashion!

Sandboxing

If you run a games arcade or otherwise want to ensure that games are isolated from the parent page, the well-nigh important indicate is to run the games on a different origin to the parent page. For instance if the parent page is on https://www.myarcadesite.com, the iframe should point to games hosted on some other origin like https://games.myarcadesite.com. The browser's same-origin security policy will prevent games being able to admission any storage or content on the domain www.myarcadesite.com.

For further isolation, you can utilize the sandbox attribute of the iframe tag. This allows for further locking downward of capabilities similar opening popups, navigating the acme frame, and then on. For more data see the iframe tag on MDN. At a minimum the sandbox attribute must contain let-scripts for the game'due south JavaScript to run. If the game is on a different origin to the parent folio, you can as well apply allow-same-origin.

Controlling framing

You may wish to limit which websites are allowed to brandish your game in an iframe. Alternatively yous may wish to block the ability to display your game in an iframe at all, ensuring it tin merely be played when directly visiting its URL.

In modern browsers, you can command this past sending a Content-Security-Policy HTTP header with a frame-ancestors directive. For example you can set this to 'none' to cake framing completely, or specify an origin to allow only that page to display the content in a frame.

For older browsers you tin can achieve similar results with the Ten-Frame-Options HTTP header.
