bem-neon
BEM (Block, Element, Modifier) syntax parser for Node.js, implemented in Rust.
This project was bootstrapped by create-neon.
Installing bem-neon
Installing bem-neon
requires a supported version of Node and Rust.
You can install the project with npm. In the project directory, run:
npm install --ignore-scripts
This fully installs the project, including installing any dependencies and running the build.
Building bem-neon
If you have already installed the project and only want to run the build, run:
npm run build
This command uses the cargo-cp-artifact utility to run the Rust build and copy the built library into ./bem.node
.
Exploring bem-neon
After building bem-neon
, you can explore its exports at the Node REPL:
$ npm install
$ node
> require('.').parseBEM('foo[bar,baz]\nqux')
{
name: 'foo',
modifiers: [ 'bar', 'baz' ],
elements: [ { name: 'qux', modifiers: [] } ]
}
Available Scripts
In the project directory, you can run:
npm install --ignore-scripts
Installs the project, including running npm run build
.
npm run build
Builds the Node addon (bem.node
) from source.
Additional cargo build
arguments may be passed to npm run build
and npm run build-*
commands. For example, to enable a cargo feature:
npm run build -- --feature=beetle
npm run build-debug
Alias for npm run build
.
npm run build-release
Same as npm run build
but, builds the module with the release
profile. Release builds will compile slower, but run faster.
npm test
Runs the unit tests by calling cargo test
. You can learn more about adding tests to your Rust code from the Rust book.
Project Layout
Cargo.toml
The Cargo manifest file, which informs the cargo
command.
README.md
This file.
bem.node
The Node addon—i.e., a binary Node module—generated by building the project. This is the main module for this package, as dictated by the "main"
key in package.json
.
Under the hood, a Node addon is a dynamically-linked shared object. The "build"
script produces this file by copying it from within the target/
directory, which is where the Rust build produces the shared object.
package.json
The npm manifest file, which informs the npm
command.
src/
The directory tree containing the Rust source code for the project.
src/lib.rs
The Rust library's main module.
target/
Binary artifacts generated by the Rust build.
