Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Putting you back in control of your browsing experience.

adblock-rust is the engine powering Brave's native adblocker, available as a library for anyone to use. It features:

  • Network blocking
  • Cosmetic filtering
  • Resource replacements
  • Hosts syntax
  • uBlock Origin syntax extensions
  • iOS content-blocking syntax conversion
  • Compiling to native code or WASM
  • Rust bindings (crates)
  • JS bindings (npm)
  • Community-maintained Python bindings (pypi)
  • High performance!

Getting started

adblock-rust is used in several projects, including browsers, research tools, and proxies. It may be a good fit for yours, too!

See docs.rs for detailed API documentation.

Also check the Rust example or the NodeJS example.

Optional features

The following cargo features can be used to tweak adblock-rust to best fit your use-case.

CSS validation during rule parsing (css-validation)

When parsing cosmetic filter rules, it's possible to include a built-in implementation of CSS validation (through the selectors and cssparser crates) by enabling the css-validation feature. This will cause adblock-rust to reject cosmetic filter rules with invalid CSS syntax.

Content blocking format translation (content-blocking)

Enabling the content-blocking feature gives adblock-rust support for conversion of standard ABP-style rules into Apple's content-blocking format, which can be exported for use on iOS and macOS platforms.

External domain resolution (embedded-domain-resolver)

By default, adblock-rust ships with a built-in domain resolution implementation (through the addr crate) that will generally suffice for standalone use-cases. For more advanced use-cases, disabling the embedded-domain-resolver feature will allow adblock-rust to use an external domain resolution implementation instead. This is extremely useful to reduce binary bloat and improve consistency when embedding adblock-rust within a browser.

Parsing resources from uBlock Origin's formats (resource-assembler)

adblock-rust uses uBlock Origin-compatible resources for scriptlet injection and redirect rules. The resource-assembler feature allows adblock-rust to parse these resources directly from the file formats used by the uBlock Origin repository.

Thread safety (object-pooling, unsync-regex-caching)

The object-pooling and unsync-regex-caching features enable optimizations for rule matching speed and the amount of memory used by the engine. These features can be disabled to make the engine Send + Sync, although it is recommended to only access the engine on a single thread to maintain optimal performance.
