How to host an HTML5 game
Prepare a web build, preserve asset paths and check controls, audio and saves before publishing a browser game.
An HTML5 game normally runs from a web page with JavaScript, styles, images and audio. The exact build steps depend on the purchased project, so start with its readme.
Build the project
For an npm project, install the Node.js version specified in its readme, run npm ci to use the dependency lockfile, and use the documented build command. A Construct project uses its own editor and export workflow. Do not upload dependency folders, development secrets or your working Git history.
Upload the complete web build
Publish the contents of the documented output folder, keeping index.html and relative asset paths together. Use HTTPS and the correct content types. Test the actual destination URL, especially if your game lives in a subdirectory. Case-sensitive hosts can reveal file-name mistakes that a local computer misses.
Local file or web server?
Opening index.html directly works only when the supplied build supports it. Some games need a local web server for modules, fetched data or browser security rules. Tideglass includes a portable build that supports double-click opening; check each other listing separately.
Test before sharing
Open a fresh browser session, play several levels, rotate a phone and test mute, fullscreen and save behaviour. Audio usually needs a player gesture. Local saves belong to a browser and site; moving domains does not automatically transfer progress. Check your browser console for missing files.
Keep an original backup
Retain the purchased ZIP, its licence and notices, and an untouched original build. Version your changes so you can restore a working release.
