Builds

If you don't use a package manager, you can access validate-note via unpkg (CDN), download the source, or point your package manager to the url.

validate-note is compiled as a collection of CommonJS modules & ES2015 modules for bundlers that support the jsnext:main or module field in package.json (Rollup, Webpack 2)

The validate-note package includes precompiled production and development UMD builds in the dist folder. They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. You can drop a UMD build as a <script> tag on your page. The UMD builds make validate-note available as a window.validateNote global variable.
