What is the Node.js equivalent of a PHP include?

Question

我正在寻找一种不需要常规框架的常规HTML和CSS（用于重复的组件，例如页眉，页脚，导航等）的服务器端简单解决方案。

Answer 1

You're looking for the

require()

function. Check out the documentation for this and other Node.js things here

If you want to use newer import statement, you may do so; it's not yet fully implemented in Node, but you can use it by using the .mjs extension on the file you need to import and then using the following command:

node --experimental-modules someFile.mjs

Answer 2

You can use require to require multiple files. However, since node caches the files, you will need to delete them from the cache if you want to used an un-cached version of the file.

index.js

app.get('/path', (req, res) => {
  clear()
  let headers1 = require('/headers/a.js')
  let headers2 = require('/headers/b.js')
  res.set(headers1)
  res.set(headers2)
})

// Remove from require cache
function clear() {
  delete require.cache[require.resolve('/headers/a.js')]
  delete require.cache[require.resolve('/headers/b.js')]
}

headers/a.js

module.exports = {
  'Content-Type': 'application/json'
}

headers/b.js

module.exports = {
  'Custom-Header': 'Brass Monkey'
}

I think you like require "view components". Exists multiple view engines for nodejs, for example pug , or ejs . In this case, you use include
