In-Memory typescript database

An in-memory database done using javascript map function to be able to test the data access layer of my projects.

You have either the synchronous and the asynchronous version to import into your project.

Public interface:

• insert(collection: string, entity: Entity)
• update(collection: string, entity: Entity)
• delete(collection: string, id: Id)
• find(collection: string, finder: Finder)
• findById(id: Id)
• getCollection(collection: string)
• getCollections()
• clean()

Entity is any javascript object with an id property with an Id.

Id is a string.

Finder is a function that receives an entity and returns a boolean.

Asynchronous version

The asynchronous version just wraps the synchronous version with promises.

You can pass a number to the constructor to simulate a delay in the response or set it dynamically with the added method setDelay(delay: number).

By default the delay is set to zero.
