Yeoman Generator

NPM version Build Status Dependencies

This module is a Yeoman generator for modules.

Getting Started

To use the generator, ensure that you have installed Yeoman:

$ npm install -g yo

For a general overview of Yeoman generators, see the Getting Started Guide.


$ npm install -g generator-validate-io


Once installed, navigate to the directory in which you want to place generated files and run

$ yo validate-io

The generator will provide a series of prompts and will use your answers to tailor the module files, providing a scaffold upon which you can immediately build.


The prompts are as follows...

Module Name

The module name requires the convention that the module be prefixed with This ensures consistency with the current naming of modules.

Valid names include:,,, etc. Do not include spaces or special characters in the name; e.g., validate io check @ value.

Also note that using the generator requires internet access, as module name availability is confirmed on NPM via npm-name.


You have the option to initialize the module directory as a Git repository. The default option is Y. Typing enter or y+enter will confirm initialization and do the following:

$ git init
$ git remote add origin<repo_name>.git
$ git add -A
$ git commit -m "[INIT]"

The initialization process stops short of pushing the commit to the remote repository.

Note: Git initialization assumes you have write access to the Validate-io organization on Github. If you are not already a member and are interested in contributing, contact one of the owners.


If you elected to initialize a local Git repository, you must specify the corresponding remote repository name. The default is the unique module id (e.g., --> object ).


Enter the primary author's name; i.e., in all likelihood that will be your name.


If you have chosen to initialize the directory as a Git repository, the default will be the email associated with your Github account. This email should be a correspondence address for those individuals wanting to contact you directly with their questions and comments.

If the Github email address is fine, just type enter.


Enter the license holder for this module. The default is your name, but this could be the organization for which you work (say, if they are helping sponsor development) or some other entity.

If the default option is fine, just type enter.


Enter the module description.


Once you have answered all prompts, you will have the following scaffold:

    - index.js
    - index.js
    - test.js


These are standard fare. If you notice that files are neither tracking in Git nor making their way onto NPM, consult .gitignore and .npmignore. The scaffold includes a .travis.yml file for continuous integration purposes. Visit Travis-CI to setup running builds.


The Makefile includes methods to run tests and generate notes. To see TODOs and FIXMEs,

$ make notes


The default license is the MIT license.


The generator creates a scaffold package.json, using the module name to generate the Github repository urls. You need to manually add keywords and any additional dependencies.


The generator includes a file. Use this file for general TODOs which are not tied to any particular file line.

The is a scaffold. You should add to the usage and example code sections.


The main library file lib/index.js includes a skeleton constructor. The file includes a dummy method (foo).


The generator creates a skeleton test file. Aim for 100% test coverage.


The generator creates an empty directory for benchmarks. Should the module warrant benchmarks, include the benchmark files in this directory.


The examples/index.js file should be modified to showcase the module and should correspond to the example provided in the README.

Node Modules

The generator will automatically run npm install and install any node modules used by the scaffold. If you need any additional dependencies,

$ npm install <module_name> --save

or development dependencies (either for testing or examples)

$ npm install <module_name> --save-dev


If you opted to initialize the module as a Git repository, you will need to manually push changes to Github.

$ git push origin master

By default, the generator generates a Travis-CI *.yml file for continuous integration and uses Coveralls for tracking code coverage over time.



Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov
