I am making my first Sapper app and the pages are all in routes. I am now extracting the content into a separate directory and unsure if I'm doing anything right.

Here is an excrept from my directory structure:

content
|- index.md
|- services.txt
|- about
 |- index.md
 |- technologies.html
routes
|- index.html
|- services.html
|- section-[section].json.js
|- about
 |- index.html
 |- technologies.html

I've made JSON interface section-[section].json.js that is used to request content. The content of sectionX can be in file content/sectionX.ext with whatever extension and the content is also parsed through marked if it's a .md file.

This is how I am loading the content in my routes/services.html:

<script>
export default 
 preload() 
 return this.fetch('section-services.json').then(r => r.json()).then(section => 
 return section;
 );
 

</script>

Nested files are requested using dot notation, i.e. about.technologies could be resolved either to file content/about/technologies.ext or content/about/technologies/index.ext (similar to how sapper resolves URIs to files).

The part that I would like to have reviewed is my routes/section-[section].json.js. This is the file that receives a section name (with slashes replaced by dots) and returns the content, parsed if it's markdown.

import fs from 'fs'
import path from 'path'
import marked from 'marked'

function getFileFromDir(file, directory)

 const filesInDir = fs.readdirSync('content/'+directory, withFileTypes: true)
 .filter(f => f.isFile() && file == path.parse(f.name).name)

 if (filesInDir.length)
 
 let fileName = 'content/'

 if (directory.length)
 fileName += directory + '/'

 fileName += filesInDir[0].name

 return fileName
 

 return null


function getFile(path) 

 path = path.split('.')

 // First try to get the named file
 let file = getFileFromDir(path[path.length-1], path.slice(0,-1).join('/'))
 if (file)
 return file

 // Assume that path is a directory and look for index
 file = getFileFromDir('index', path.join('/'))
 if (file)
 return file

 return null


export function get(req, res) 
 let file = getFile(req.params.section)

 if (!file)
 return 'Failed to fetch content of section ' + req.params.section

 let content = fs.readFileSync(file, 'utf8')

 if ('.md' == path.extname(file))
 content = marked(content)

 res.writeHead(200, 
 'Content-Type': 'application/json',
 'Cache-Control': `max-age=$30 * 60 * 1e3`
 )

 content = JSON.stringify(content)

 res.end(content)

My experience with Node is also fairly limited, any tips appreciated!
