[Tools] Batch Create Markdown Files from a Template with Node.js and Mustache

Creating Markdown files from a template is a straightforward process with Node.js and Mustache. You can define a template, load it into your script, then push whatever data you have into your template, then write the files back out. Node.js built-in filesystem tools allow you to read and write the files while Mustache helps you to push the data into the template.

 

Install:

npm i --save mustache

 

index.js:

let fs = require("fs")
let { render } = require("mustache")

let template = fs.readFileSync("./template.md").toString()

people.forEach(person => {
  let output = render(template, person)
  fs.writeFileSync(`./people/${person.name}.md`, output)
})

 

let fs = require("fs")
let { render } = require("mustache")

let people = [
