[NJS] Creating a new post

Last post in the series is about creating a new post. This wasn't really needed, since the whole point of having my blog in Dropbox was to use any markdown editor I desire, save the file, run the sync command, and have it live, but for the sake of learning, I went ahead and added this feature too.

First, the routes:

router.get("/create/" + process.env.MY_SYNC_KEY, function(req, res) {
  res.render("create-post", {
    title: "Create",
    metadata: "Create a post"
  })
})
 
router.post("/create", function(req, res) {
  if (req.params.token != process.env.MY_SYNC_KEY) { res.redirect("/"); return }
  const body = req.body
 
  // Create the file first, if it doesn't work, stay on the page.
  Dropbox.createFile(body).then(function(data) {
    if (!data) { res.end(); return }
 
    res.redirect("/cmd.sync/" + process.env.MY_SYNC_KEY)
  })
})

Then the createFile function:

const request = require("request")
Dropbox.createFile = function(body) {
  return new Promise(function(resolve) {
    const fileContents = body.title + "\n\n" + body.body
    const fileName = "posts/" + body.datetime + "-" + body.title + ".md"
 
    const options = {
      method: "PUT",
      url: "https://api-content.dropbox.com/1/files_put/auto/" + fileName + "?overwrite",
      headers: {
        "Content-Type": "text/plain",
        Authorization: "Bearer " + process.env.DB_ACCESS_TOKEN
      },
      body: fileContents
    }
 
    request(options, function(err) {
      if (err) {
        console.log("Creating " + fileName + " failed.")
      }
      else {
        resolve(true)
      }
    })
  })
}

And lastly, the view is just a <form method="post" action="/create"> with some text inputs and an <input class="button" type="submit">.

I hope I managed to explain things properly throughout the series, I hope I haven't forgotten anything, and if there's anything to fix or improve, don't hesitate to contact me; I'd be more than glad to discuss about anything.
