node.js - koa2 template engine rendering failure

Question

The code is as shown in the figure. The expected result should be that the title has changed and the title is named node.
But in actual operation, the title is <%= title %>, which means the template engine does not work?

Answer 1

It seems that your index.js does not have a template engine set? Like the jade template engine, html files should be .jade files, not .html.

Answer 2

I agree with you, should I save the index.html file as an index.jade file? The jade template has been upgraded, save it as index.pug and try it.

Answer 3

gg, my mistake, the brackets were placed in the wrong place, disturbing everyone.

app.use(views(path.join(__dirname, './views'), {
  map: {
    html: 'underscore'
  }
}))

Just change it to this way
