Useful TypeScript Functions

A dependency-free collection of useful functions for applications in TypeScript. (Actually, you need some peer libraries if you use some of the functions). Written in Typescript.

• Objects for working with objects
• Functions run asynchronous functions one after each other
• Logger a structured log file generator which can easily be tested
• Server to simplify creation of express.js servers and routers
• Files to help handle files, especially image previews
• Mailer for sending html templated emails easily
• Streams for easier handling of streams of data

Upgrade from version 3

Version 4 of useful-typescript-functions only works with ESM.

Upgrade from version 2

There are some breaking changes of version 3.

• If you use Server, you should have a look into the this upgrade info.
• Previously deprecated functions flattenObject() and inflateObject() are now removed. You now need to move to flatten and inflate() now.
• Instead of using CSVLogger to read and write CSV files, you should now use Streams module and its CSV related transforms.
• The CSVLogger module is now removed in favour of using Logger and its function createCSVTransport(). Read about that here
