Crate npm_rs

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()?;

Structs

Npm

This struct is used to execute npm commands. Can be created from NpmEnv of using Default.

NpmEnv

This struct is used to create the enviroment in which npm will execute commands. NpmEnv uses Command so it takes all the env variables in your system.

Enums

NodeEnv

This enum is used to determine the desired NODE_ENV variable value. Its value by Default is NodeEnv::Development
