Visual Field

I developed Visual Field (https://visualfield.org) in late 2019 as an attempt to build a text and spatial enabled true server-less database functioning entirely within the browser. It is a recent example of a software application that I have developed. I hope you can find it useful in your project.

Visual Field is largely written in vanilla HTML and vanilla javascript but I also utilized some fantastic open source javascript and css libraries. In these times where CORS enabled open datasets are now ubiquitous, I think having a standards based native SQL engine available in web browsers is perhaps long overdue. Visual Field is currently built upon WebSQL - which is an excellent browser based database. But WebSQL does have limitations - such as limited text and spatial capabilities. Visual Field attempts to fill in that missing ground. My hope is that the current W3 impasse in relation to WebSQL (still at 2019) will eventually get resolved and us developers can ultimately get access to a fully fledged native SQL engine running directly in the browser (whether that be WebSQL or some other standards based SQL engine).

If you get inspired when you play with Visual Field, please get in touch via the email address above.
