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 = [ { name: "Luke Skywalker", height: "172", mass: "77", hair_color: "blond", skin_color: "fair", eye_color: "blue", birth_year:
