Typescript / pattern for node backend

Hi

I want to build personnal project with good practise ("enterprise grade"), in all my project i think that i've some lack about organisation and property of code.

I've a server with gitlab, jenkins, jira for continous integration and i will do test driven development.

I'm planning to use typescript for node back-end and react front-end for safety check and have better structure if a "team" need to work with it.

What did you think about using typescript at server side (with express server), pro cons ?

Did you know good pattern practise for server side (repository pattern ? i will use mongodb database and mongoose) ?

Thank's
