As you likely know, you will need to be very careful when developing web-based applications for the resource-constrained devices you mention. A typical bloated web app as made by most companies will often not run well in resource-constrained environments like many ARM SOCs. I would encourage you to approach the app design process with an extremely minimalist approach, striving to avoid libraries and use vanilla JS as much as possible, use tiny assets, and keep allocations to a minimum (maybe consider object pools for certain applications). If you use a minimal framework, Mithril JS might be a good choice, or domvm, or something similarly minimal. You probably want to stay away from React and Angular.
