install-em v0.0.4

install-em

NodeJS utility for dependency management.

Example

manifest.json

{
    "production": {
        "react": "^16",
        "react-dom": "^16"
    },
    "build": {
        "webpack": "^5",
    },
    "code-quality": {
        "eslint": "latest"
    }
}

terminal:

install-em -m manifest.json -t /Users/me/example/ build code-quality

CLI

Options

-m, --manifest: path to directory/json-file, where manifest is located (looks for package.json, if directory is given, and looks for ./package.json of current directory, if no parameter given)

-t, --target: installation destination directory (would create node_modules there)

-f, --force: reinstall dependencies, even they are already installed.

Custom groups

You free to use any group names, that satisfy /[a-zA-Z0-9_-]+/.

Group aliases

Also, there is some aliases to use with standard package.json files:

-p, --prod: use dependencies group

-d, --dev: use devDependencies group

-o, --optional: use optionalDependencies group

example:

{
    "dependencies": {
        "lodash": "4"
    },
    "devDependencies": {
        "rimraf": "latest"
    },
    "foo": {
        "left-pad": "^1.3.0"
    }
}

install-em -p --dev -f foo

executes in current directory:

npm install --no-save --force lodash@4 rimraf@latest left-pad@^1.3.0

installDependencies(dependencies, path[, opts])

dependencies (Array): array of name/version pairs, like [name, version, name, version]

path (string): installation destination folder

opts (object)

opts.force (boolean): reinstall dependency, even it's already installed in destination directory (false, by default)
