let template = ejs.compile(str, options);
template(data);
// => Rendered HTML string

ejs.render(str, data, options);
// => Rendered HTML string

ejs.renderFile(filename, data, options, function(err, str){
    // str => Rendered HTML string
});


Options配置项
  • cache Compiled functions are cached, requires filename
  • filename Used by cache to key caches, and for includes
  • context Function execution context
  • compileDebug When false no debug instrumentation is compiled
  • client Returns standalone compiled function
  • delimiter Character to use with angle brackets for open/close
  • debug Output generated function body
  • _with Whether or not to use with() {} constructs. If false then the locals will be stored in the locals object.
  • localsName Name to use for the object storing local variables when not using with Defaults to locals
  • rmWhitespace Remove all safe-to-remove whitespace, including leading and trailing whitespace. It also enables a safer version of -%> line slurping for all scriptlet tags (it does not strip new lines of tags in the middle of a line).
  • escape The escaping function used with <%= construct. It is used in rendering and is .toString()ed in the generation of client functions. (By default escapes XML).
  • outputFunctionName Set to a string (e.g., 'echo' or 'print') for a function to print output inside scriptlet tags.
  • async When true, EJS will use an async function for rendering. (Depends on async/await support in the JS runtime.
