从文件加载ES6模板字符串

Question

Let me explain my actual problem. I have a template string which could look like this:

/${name}
  get
  post
  /{id}
    get
    /file-content
      get
      post

The indentation has to remain untouched.

Now if I were to use such a template string it might look like this:

function test(arr) {
    let ret = []
    arr.forEach(
        function(name) {
            return `/${name}
  get
  post
  /{id}
    get
    /file-content
      get
      post`
            return ret
        }
    )
}

Looks pretty ridiculous, right? I could of course put extra spaces into my template to match my code indentation, but then I'd have to perform unnecessary operations on the string afterwards to normalize it again.

So my idea was to move the template string to an external file and require that file whenever I need the template string.
But require can't be used for that problem because it's nothing more than a text file and I certainly don't want to read that file from disk every time I need it and perform an eval on it.

I could think of several workarounds for this problem, but I just cannot seem find a satisfying solution.

Answer 1

How about this:

// template.js
module.exports = name => `
/${name}
  get
  post
  /{id}
    get
    /file-content
      get
      post
`.trim()

// app.js
const template = require('./template')('name');
