Custom Global Data Coming soon in v1.0.0 #

In addition to Global Data Files global data can be added to the Eleventy config object using the addGlobalData method. This is especially useful for plugins.

The first value of addGlobalData is the key that will be available to your templates and the second value is the value of the value returned to the template.

Example #

module.exports = function (eleventyConfig) {
// Values can be static:
eleventyConfig.addGlobalData("static", "static");
// functions:
eleventyConfig.addGlobalData("function", () => new Date());
// or async :
eleventyConfig.addGlobalData(
"async",
() =>
new Promise((resolve) => {
setTimeout(resolve, 100, "foo");
})
);
};

Sources of Data #

When the data is merged in the Eleventy Data Cascade, the order of priority for sources of data is (from highest priority to lowest):

  1. Computed Data
  2. Front Matter Data in a Template
  3. Front Matter Data in Layouts
  4. Template Data Files
  5. Directory Data Files (and ascending Parent Directories)
  6. Global Data Files
  7. Custom Global Data
