● WebAssembly for Web developers
● WebAssembly with Rust
● Demo

4. WebAssembly

5. WebAssembly

6. WebAssembly
● New transformation in Web development.
● A new capability to Web and web browsers.
● Fast, portable and secure.
● Safe and Isolated execution and memory.
● Compile to WASM from any supported language
○ C, C++, Go, Rust
● Interpret in Many languages:
○ JavaScript,Node, Go, Rust, C, C++

7. Efficient and Fast
WebAssembly aims to execute at
native speed by taking advantage of
common hardware capabilities
available on a wide range of
platforms.
01
Open and debuggable
WebAssembly is designed to be
pretty-printed in a textual format for
debugging, testing, experimenting,
optimizing, learning, teaching, and
writing programs by hand.
03
Safe
WebAssembly describes a
memory-safe, sandboxed execution
environment that may even be
implemented inside existing
JavaScript virtual machines.
02
Open web platform
WebAssembly is designed to
maintain the versionless,
feature-tested, and
backwards-compatible nature of the
web.
04
WebAssembly features

9. WebAssembly for Web developers
● Existing code to web.
● like Autocad, Various Games, and image processing tools, etc.
● Ecosystem

11. Web Development Today
● Browser Compatibility
● Disparate build
environment
● TypeScript,
JavaScript,
CoffeeScript, X-to-JS
CodeGen.
As SPA’s gets better and
more powerful, gets
everything gets slower.
● Slow builds.
● Bloated Frameworks.
● Code Performance.
● Browser Issues.
● An infinite number of
ways to solve every
problem.
● Too many libraries, too
much to learn
node_module directory
is a meme.
● Rapid ecosystem
change.
Fragmented Slow Overwhelming

13. WebAssembly vs Javascript

14. WebAssembly with Rust
● Get benefit of unique Rust features.
○ Memory safety
○ Efficiency
○ Portability
● Wasm pack, Wasm_bindgen.
● Powerful community.
