What is expected?:
I would like to convert the below listed directory structure
into a single JSON file.
The directory structure contains JSON files
that are supposed to be included in
the output file as well.
Limitations:
Node.js
Questions:
What would be a good/efficient
way to generate the desired output,
using Node.js + Modules?
Logically, what would be the
necessary steps?
Directory structure:
CMS/ ├── en/ | ├──brand_one/ | | ├──footer.json | | ├──header.json | ├──brand_two/ | | ├──footer.json | | ├──header.json | ├──brand_three/ | | ├──footer.json | | ├──header.json ├── de/ | ├──brand_one/ | | ├──footer.json | | ├──header.json | ├──brand_two/ | | ├──footer.json | | ├──header.json | ├──brand_three/ | | ├──footer.json | | ├──header.json ├── fr/ | ├──brand_one/ | | ├──footer.json | | ├──header.json | ├──brand_two/ | | ├──footer.json | | ├──header.json | ├──brand_three/ | | ├──footer.json | | ├──header.json ├── es/ | ├──brand_one/ | | ├──footer.json | | ├──header.json | ├──brand_two/ | | ├──footer.json | | ├──header.json | ├──brand_three/ | | ├──footer.json | | ├──header.json [...]
Desired output:
// content.json
{
"en":[
{
"brand_one":{
"footer":{
"val": "value",
[...]
},
"header":{
"val": "value",
[...]
}
},
"brand_two":{
"footer":{
"val": "value",
[...]
},
"header":{
"val": "value",
[...]
}
},
"brand_three":{
"footer":{
"val": "value",
[...]
},
"header":{
"val": "value",
[...]
}
}
}
],
[...]
}

You could create a function to convert a directory to an object, with a property for each dir / file.
This would then be called recursively to walk the entire tree, in this case using the fs/promises functions.
const fs = require('fs/promises');
const path = require('path');
async function walkDir(dir, result = {}) {
let list = await fs.readdir(dir);
for(let item of list) {
const itemPath = path.join(dir, item);
let stats = await fs.stat(itemPath)
if (await stats.isDirectory()) {
result[item] = {};
await walkDir(itemPath, result[item]);
} else {
const fileName = path.basename(item, path.extname(item));
result[fileName] = JSON.parse(await fs.readFile(itemPath, { encoding: 'utf-8'}));
}
}
return result;
}
async function testWalkDir() {
let result = await walkDir('./CMS')
console.log("Result:", JSON.stringify(result, null, 2));
}
testWalkDir();
Assuming each file looks like
{
"some_key": "some_val"
}
I get a result that looks like so:
{
"en": {
"brand_one": {
"footer": {
"some_key": "some_val"
},
"header": {
"some_key": "some_val"
}
},
"brand_three": {
"footer": {
"some_key": "some_val"
},
"header": {
"some_key": "some_val"
}
},
"brand_two": {
"footer": {
"some_key": "some_val"
},
"header": {
"some_key": "some_val"
}
}
}
}
