Shared library for server (nodejs hosted) utilities.

base

The Serverbase library pulls together the core set of libraries required by the various nodejs-hosted components of DRA2020. This includes:

• the nodejs hosted server
• serverless lambda functions
• command line utilities run under nodejs

These libraries are all packaged in this repository. Normally they are included like this:

import { DB, Lambda } from '@dra2020/baseserver';

Then the various functions of the different sets are available under their appropriate symbol.

These libraries are used only on the server (or nodejs-hosted command line utilites):

• DBAbstract: A database abstraction interface, exposed as FSM classes.
• Storage: A blob storage abstraction interface, exposed as FSM classes.
• JS: A set of classes for doing stream-based reading and writing of JSON.
• FsmFile: A set of utility classes for exposing file operations (e.g. mkdir) as FSM-compatible classes.
• LogServer: The server implementation of the logging interface, supports saving the logs up to a blob storage.
• S3: An implementation of the storage abstraction on top of AWS S3, exposed as FSM classes.
• DBDynamo: An implementation of the DB abstraction on top of AWS DynamoDB, exposed as FSM classes.
• Lambda: An interface for invoking AWS lambda functions in a consistent way, exposed as FSM classes.
