Helpers

To add custom helpers or otherwise interact with Handlebars directly, create a file named patternlab-handlebars-config.js in the root of your Pattern Lab project, or override the default location by specifying one or several glob patterns in the Pattern Lab config:

  {
    ...
    "engines": {
      "handlebars": {
        "extend": [
          "handlebars-helpers.js",
          "helpers/**/*.js"
        ]
      }
    }
  }

Each file should export a function which takes Handlebars as an argument.

module.exports = function(Handlebars) {
  // Put helpers here

  Handlebars.registerHelper('fullName', function(person) {
    // Example: person = {firstName: "Alan", lastName: "Johnson"}
    return person.firstName + " " + person.lastName;
  });
};
