md-links-gavp/src/get-links.js

A library that finds and validates the status of the links inside a markdown file

const fs = require('fs');
const marked = require('marked');

// reads the file
const fileContent = (route) => fs.readFileSync(route, 'utf-8');

// gets the links in Md files
const getLinks = (filePath) => {
  const arrayLinks = [];
  filePath.forEach((files) => {
    const readMd = fileContent(files);
    const renderer = new marked.Renderer(); // understanding Renderer https://dustinpfister.github.io/2017/11/19/nodejs-marked/
    renderer.link = (href, title, text) => {
      if (!href.startsWith('#')) {
        arrayLinks.push(
          {
            href: href,
            text: text.substr(0, 50),
            file: files,
          },
        );
      }
    };
    marked(readMd, { renderer });
  });
  return arrayLinks;
