Set your own Library instance

New in Eleventy v0.3.0: 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);
};

New in Eleventy v0.3.0: See “Options” on the EJS home page.

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