Hello, I am a student, and I want to build a simple web application that allows students to write and publish posts ( like Twitter ) and use recommendation engines to show other students' posts that match or are similar to the topics of your published posts ( or even the posts you liked ).

the backend is with ExpressJs.

I don't know how to start and what to learn exactly, so any help, suggestions or advice I'll be grateful.

Hello Mohamed,

You might want to start with our [GraphAcademy courses](https://graphacademy.neo4j.com/) to get the basics.

Also, William Lyon just released a book about [Full Stack GraphQL Applications with React, Node.js and Neo4j.](https://neo4j.com/blog/free-book-full-stack-graphql-applications/) You can get [a pdf for free.](https://neo4j.com/fullstack-graphql-applications-react-nodejs-neo4j/) You can join [his book club live sessions](https://neo4j.com/events/list/?tribe_eventcategory%5B0%5D=26929). He goes over a chapter a week.

More specifically on Twitter, [Mananai Saengsuwan](https://mananaisaengsuwan.medium.com/?source=post_page-----6e3d38042af1--------------------------------) wrote an article using Neo4j to analyze Twitter data.

Hope this helps,

Yolande
