You can use our typescript client for everything not only for Schemas. Here is a section that has examples on how to use it https://docs.tigrisdata.com/typescript/. Please let us know if anything is confusing.
Didn't explain myself well, meant I want to use Javascript only and maybe typescript only for the schemas. I understand that Tigris exposes a HTTP endpoint and is all json but wondered how well the Typescript SDK will play for pure Javascript development.
