This is a Typescript library for writing web-based psychology experiments in a sane and reproduceable way. Parts of it are inspired by jsPsych, and it's possible this library has no advantages over jsPsych, but it exists and I'm writing it up.

Prior to writing this library I'd been using psiTurk with custom js, and I'd also experimented with jsPsych. Here were the pain points I was hoping to address:

• usable as a single-page webapp - I wanted to be able to run the experiment on a static web host and outsource data-storage to a database-as-a-service like firebase. In psiTurk the example js seems to be an afterthought, and the whole thing is mturk centric. Running an experiment on-site or on a non-mturk platform is a hacky special case scenario.

• promise-oriented api - I wanted the async parts to be composable

• modern dev tooling - I wanted to be able to install the library via npm, and be able to install modular components (different experiment types, for example) via npm as well.

• choose between dynamic jsPsych-style timeline or a strongly typed one

• someday host the whole thing on aws lambda? - just run a script that has access to your aws creds and the whole thing is run & hosted?
