fql

Rust implementation of a lexer and parser for CrowdStrike Falcon Query Language (FQL).

You'll need rust and its package manager cargo. You can install them here.

Once you have those, you will be able to run the tests and the demo CLI.

• Run the tests with cargo test
• Run the CLI with cargo run -- --help

The fql-ts crate exposes bindings so the core fql crate can be used from JS/TS in the browser.

• wasm-pack is needed to build the fql-ts package. You install it by running cargo install wasm-pack in your terminal.
• node and npm are needed for the demo server. You can download the installer here

1. Enter the fql-ts directory
2. Run wasm-pack build --target web to build the NPM package.
3. cd ../fql-web-demo to switch to the web demo directory.
4. Run npm install to install the dependencies from the package.json file
5. Run npm run start to start the dev server
