1. Rust for Node.js Developers Giovanny Gongora / @gioyik
2. OUTLINE • What is Rust? • Why using Rust with Node.js • Rust inside Node.js • FFI on Node.js • Let’s do it • More ways?
3. WHAT IS RUST? 1. A systems programming language 2. It focuses on speed, safety and concurrency 3. Great fit to write programs with specific time requirements 4. Ability to write low level code, like device drivers 5. No garbage collector
4. What does it look like? You can run this on https://play.rust-lang.org if you don’t have Rust installed
5. WHY SHOULD I CARE?
6. WHY USING RUST WITH NODE.JS 1. Performance 2. Parallelism 3. Bindings
7. ANY REAL ADVANTAGE WE COULD SEE? Yes, but not today
8. RUST INSIDE NODE.JS (really?)
9. THE PROBLEM “Start ten threads. Inside each thread, count from one to five million. After all then threads are finished, print out ‘done!’”
10. Let’s create a new cargo project configure Cargo.toml
11. Edit the lib Build it
12. Create your node file Check the output
13. LET’S TRY A LESS COMPLEX EXAMPLE!
14. Let’s create a new cargo project configure Cargo.toml
15. Edit the lib Build it
16. Create your node file profit!
17. MORE WAYS?
18. LET’S TRY A COMPLEX EXAMPLE!
19. NEON Neon is a Rust bridge to the Node.js platform: an API (and a set of tools) for implementing binary Node modules in Rust
20. RUNO [PROTOTYPE] RuNo bridge is a command line tool which generates C++ boilerplate add-on code to call Rust library from.
21. CONCLUSIONS
22. SHOULD I TRY RUST?
23. SO, USE RUST INSTEAD OF JAVASCRIPT ON WEB APPLICATIONS?
24. THANKS! More info at Rust Inside Other Languages Giovanny Gongora / @gioyik
