npm_rs

A library to run npm commands from your Rust build script.

Documentation

This library will aid you in executing npm commands when building your crate/bin, removing the burden of having to manually do so or by using a tool other than Cargo.

This crate provides an abstraction over Command to use npm in a simple and easy package with fluent API.

npm_rs exposes NpmEnv to configure the npm execution enviroment and Npm to use said enviroment to execute npm commands.

Examples

Manual NODE_ENV setup

// build.rs

use npm_rs::*;

let exit_status = NpmEnv::default()
       .with_node_env(&NodeEnv::Production)
       .with_env("FOO", "bar")
       .init_env()
       .install(None)
       .run("build")
       .exec()?;

Automatic NODE_ENV setup

// build.rs

use npm_rs::*;

let exit_status = NpmEnv::default()
       .with_node_env(&NodeEnv::from_cargo_profile().unwrap_or_default())
       .with_env("FOO", "bar")
       .init_env()
       .install(None)
       .run("build")
       .exec()?;
