If I wanna use extend/include, a block, macro or others in nunjuck, config such as follow:

Directory:

   /
   ├─ app.js
   │
   └─ tpl
       │
       ├─ com.html
       │
       └─ error.html

app.js:

app.use(koaError({
    //...
    engine: 'nunjucks',
    template: path.join(__dirname, 'tpl/error.html'),
    options: {
        settings: {
            views: path.join(__dirname, 'tpl') // use other tpl file in tpl
        },
        helpers: {
            stringify(o) {
                return JSON.stringify(o);
            }
        }
    }
}));

tpl/error.html:

<!DOCTYPE html>
<html>
  <head>
    {% include "./com.html" %}
  </head>
  <body>
    <!--  use helpers.stringify(obj) here -->
    <!-- ... -->
  </body>
</htm>

tpl/com.html:

<link rel="stylesheet" href="/css/normalize.css" />

You can also define some custom filters in the following way：

app.js

const nunjucksEnv = new nunjucks.Environment(
    new nunjucks.FileSystemLoader(path.join(__dirname, 'tpl'))
);

nunjucksEnv.addFilter('stringify', (...args) => {
    return JSON.stringify(...args);
});

app.use(koaError({
    //...
    template: path.join(__dirname, 'tpl/error.html'),
    options: {
        nunjucksEnv // custom nunjucks env
    }
}));

error.html

<!DOCTYPE html>
<html>
  <head>
    {% include "./com.html" %}
  </head>
  <body>
    <p>{{ request | stringify }}</p>
    <!-- ... -->
  </body>
</htm>
