Using own libraries (re-use code) in multiple scripts

[some-user123]

I'm new to flow based programming and wondering how to use my own library in multiple scripts. Is there a default pattern how to do that?

What I'm thinking of? E.g.

• When using a RESTful API, I'd like to wrap specifics of the API in a class (let's assume typescript). Apparently, this class would be used in all scripts that use the API.
• When accessing a database using an ORM like GORM (in Go) I'd like to reuse the definition of the structs in multiple scripts.
• When accessing a database using an PRM like Prisma (in Typescript), I have to generate the client (prisma generate) before being able to use it
• When accessing a GraphQL API typically there is code generated as well based on the schema (*)

* Maybe GraphQL would also be an option to be supported natively...
