A Simple Noscript Boilerplate

wasm_bindgen Rust boilerplate for writing and deploying Noscript. This is also a noscript example that filters Nostr text note events with the Japanese language. Other language filtering is available at branches

---

required:

• wasm-pack installed https://github.com/rustwasm/wasm-pack

Code Structure

• script is the crate of Noscript source code, which is what will be compiled to wasm bytecode that saved on relay.
• deploy is the crate of Noscript deploying tool, turn the script source code to a special event and then sign it and send it to relay.
• index.js is the js test environment which creates a fake runtime interface, and runs the wasm script in browser for test

Compile

cd script && wasm-pack build --target web

Test

yarn && yarn serve

check browser http://localhost:8080/ see console

Deploy Noscript

create a config.toml file inside deploy folder and paste your Nostr private key

cd deploy
cp example-config.toml config.toml

// generate and sign event
cargo run --bin deploy

What is Noscript?

Noscript means Nostr Script, which refers to the idea that we can put code on Nostr protocol(save the code in a special kind of Event, sign it and send it to the relay, basically), a Noscript is a piece of code to be running in a standard environment provided by Nostr client so there is no central control but user-generated alternatives, it can be used to provide custom feeds/recommend algorithms and so much more.

right now we are experimenting Noscript with wasm runtime under the Nostr web client flycat.club
