Fortunately, applications such as v make it possible to run a webserver in your web browser to serve content held locally by uploading it to the browser and serving it from there:įor running simple applications, installing something like v as an app so you can run it offline is really handy when it comes to not requiring a user to run their own webserver. there is no requirement on the provider to provide a code execution server: a static web server is all that is required to provide the environment to the user.Ī Brief Aside – Serving Webpages Locally Without a Webserverįor purely local running, there may be requirement for the the user to run a local webserver to serve the environment: if you double click an HTML file on your desktop and open it in a broweser with a URL starting file://, the browser may well throw CORS (cross-origin) security errors as it tries to load the page.there is no requirement on the user to install any software on their desktop: all they need is a web browser, a network connection to download the environment, and a powerful enough computer to run the application in the browser.If you want to try it out, there’s a simple demo page here:Īpplications moving off-the-server and into the browser is really handy in many educational contexts because it means: Databases can be loaded from an uploaded file, or retrieved from a remote URL. The sql.js package provides a WASM compiled version of SQLite that runs purely in the browser. See also: Seven Ways of Making Use of SQLite. Several ways of working with SQLite in the browser exist the following does not claim to be a complete list, just a representative sample, and includes: In this post, I’ll review a couple of WASM compiled databses that you can run purely within a browser: SQLite and Duck.db. It worked as a general SQL database client, or could be used to manage and query a SQLite database powered by sql.js. Several years ago, in a post on Asking Questions of CSV Data, Using SQL In the Browser, I described a rather nifty application called franchise, (from the repo, it seems to have been deprecated for some time, or at least, is no longer actively maintained there).
