Why is dependency in package.json prefixed with @polymer?

When looking at this package.json I see two versions for sinonjs:

  "dependencies": {
    "@polymer/sinonjs": "^1.14.1",
    ...
    "sinon": "^2.3.5",
    ...
  },

What is the difference between sinon and @polymer/sinonjs?

Solution

  • Node packages that start with @namespace are scoped packages. Typically this means an organization that wants a standardized naming convention for all of their packages that might have common names already taken in the global namespace.

    In your example the organization is Polymer who has their own published version of sinon. As to why Polymer has their own published package of Sinon you'd have to ask them. The description suggests it's a workaround to access the Bower version of Sinon. That workaround probably wont be needed once Polymer makes the jump to NPM.

    SinonJS proxy repository for the BowerJS package manager
