What is npm-package-json-lint?

npm-package-json-lint helps enforce standards for your package.json file. This helps to ensure that your files are of the highest standard and quality. It is also customisable to match your specific project guidline requirements/desires. It has support for both command line and programmatic usage. Currently it can check for:

• validity of data types in nodes. Ex: name should always be a string.
• whether a string is a lowercase
• whether a version number is a valid
• the presence of a given module
• the presence of a pre-release version of a module
• the presence of an author
• the presence of any bugs
• valid dependencies
• valid licenses
• and much more!
