示例1: note

async function note(options: Options) {
  if (!options.topic) {
    console.error('No topic given!')
    process.exit(1)
    return
  }

  if (!(await topicExists(options.topic))) {
    console.error(`The topic "${options.topic}" does not exists`)
    process.exit(1)
    return
  }

  const date = new Date()

  const publishedAt = date.toISOString()
  const text = '_Content goes here_'
  const mdx = `---\npublishedAt: ${publishedAt}\n---\n\n${text}\n`

  const dir = await uniqueNote(options.topic, date)
  await fs.promises.mkdir(dir, { recursive: true })

  const file = `${dir}/index.mdx`
  await fs.promises.writeFile(file, mdx)

  console.log(`New note created at: ${file.replace(path.resolve(__dirname, '..'), '')}`)
