EJS Options #

See “Options” on the EJS home page.

module.exports = function(eleventyConfig) {
  eleventyConfig.setEjsOptions({
    // use <? ?> instead of <% %>
    delimiter: "?"
  });
};

As an escape mechanism for advanced usage, pass in your own instance of the EJS library using the Configuration API.

module.exports = function(eleventyConfig) {
  let ejs = require("ejs");
  eleventyConfig.setLibrary("ejs", ejs);
};

Feature	Syntax
✅ Include (Preprocessor Directive)	`<% include /user/show %>` looks for `_includes/user/show.ejs` (the leading slash is important). Does not process front matter in the include file.
✅ Includes (Relative Path, Preprocessor Directive)	Relative paths in `ejs` can leave off the leading slash `/` or use `./` to use the template’s directory or `../` for the template’s parent directory: `{% include 'user/show' %}` or `{% include './user/show' %}` looks for `./user/show.ejs` from the template’s current directory. Does not process front matter in the include file.
✅ Include (pass in Data)	`<%- include('/user/show', {user: 'Ava'}) %>` looks for `_includes/user/show.ejs`. Does not process front matter in the include file.
