Gatsby New Post CLI Script

This is a small script for creating new posts for markdown generated blogs like Gatsby.

I looked around for a script to use until I decide on which JAMStack CMS I want to implement but every example script I found seemed to have a lot of dependencies.

So I decided to make one myself using core nodejs features.
The script uses readline and fs which are both core nodejs functions.

const fs = require('fs')
const readline = require('readline')
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
})

Use readline.createInterface to listen on process.stdin.

const dateNow = new Date()

Use Date() to get current date and time for the blog posts published time.

const blogPostFolder = './content/posts'
const blogPostDate = `${blogPostFolder}/${year}-${month}-${day}`
if (!fs.existsSync(blogPostFolder)) {
  console.log(`ERROR: posts folder not found: ${blogPostFolder}`)
  rl.close()
  process.exit(1)
}

Check the folder specified exists, exit with error if content folder does not exist.

fs.writeFileSync(`${blogPostDate}-${title}.md`, output)
console.log(`Post ${title} was created successfully`)
console.log(`Location: ${blogPostDate}-${title}.md`)
rl.close()
process.exit(0)

Write to markdown file and give feedback to user with location of new blog post file created.
