var david = require('david');

// Your package.json
var manifest = {
  name: 'xxx',
  dependencies: {
    'aaa': '~0.0.0',
    'bbb': '~0.0.0'
  },
  devDependencies: {
    'yyy': '~0.0.0',
    'zzz': '~0.0.0'
  }
};

david.getDependencies(manifest, function (er, deps) {
  console.log('latest dependencies information for', manifest.name);
  listDependencies(deps);
});

david.getDependencies(manifest, { dev: true }, function (er, deps) {
  console.log('latest devDependencies information for', manifest.name);
  listDependencies(deps);
});

david.getUpdatedDependencies(manifest, function (er, deps) {
  console.log('dependencies with newer versions for', manifest.name);
  listDependencies(deps);
});

david.getUpdatedDependencies(manifest, { dev: true }, function (er, deps) {
  console.log('devDependencies with newer versions for', manifest.name);
  listDependencies(deps);
});

david.getUpdatedDependencies(manifest, { stable: true }, function (er, deps) {
  console.log('dependencies with newer STABLE versions for', manifest.name);
  listDependencies(deps);
});

david.getUpdatedDependencies(manifest, { dev: true, stable: true }, function (er, deps) {
  console.log('devDependencies with newer STABLE versions for', manifest.name);
  listDependencies(deps);
});

function listDependencies(deps) {
  Object.keys(deps).forEach(function(depName) {
    var required = deps[depName].required || '*';
    var stable = deps[depName].stable || 'None';
    var latest = deps[depName].latest;
    console.log('%s Required: %s Stable: %s Latest: %s', depName, required, stable, latest);
  });
}

Both getDependencies and getUpdatedDependencies return an object result, whose keys are package names. The values are objects which contain the following properties:

• required - The version required according to the manifest
• stable - The latest stable version available
• latest - The latest version available (including build and patch versions)

CLI

If you install David globally with npm install -g david, you can run david in your project directory to see which dependencies are out of date.

You can also run david --global to see your outdated global dependencies.

Update to latest

To update all your project dependencies to the latest stable versions, and save to your package.json, run:

1

david update

To update a particular project dependency to the latest stable version, and save to your package.json, run:

1

david update package-name

You can also update global dependencies to latest versions:

1

david update --global

To update all your project dependencies to the latest versions (including unstable versions), pass the --unstable flag:

1

david update --unstable

Alternate registry

1

david update --registry http://registry.nodejitsu.com/

Non-npm and SCM (Git) dependencies

If you have dependencies that are not published to npm, david will print a warning message by default. To throw an error and exit, pass the error404 option:

1

david --error404

If using david programmatically, pass error: {E404: true} in the options object.

If you have dependencies whose versions are SCM URLs, david will print a warning message by default. To throw an error and exit, pass the errorSCM option:

1

david --errorSCM

If using david programmatically, pass error: {ESCM: true} in the options object.

Specify package.json path

Use -p, --package to specify the path to your package.json.

Ignore dependencies

To tell david to ignore dependencies, add a david.ignore property to your package.json which lists the dependencies david should ignore. If using david programmatically you can also pass this as an option. e.g.

package.json

{
  "david": {
    "ignore": ["async", "underscore"]
  }
}
