Pastebin-worker

This is a pastebin that can be deployed on Cloudflare workers. Try it on shz.al.

Philosophy: effortless deployment, friendly CLI usage, rich functionality.

Features:

  1. Share your paste with as short as 4 characters
  2. Customize the paste URL
  3. Update and delete your paste as you want
  4. Expire your paste after a period of time
  5. Syntax highlighting powered by PrismJS
  6. Display markdown file as HTML
  7. Used as a URL shortener
  8. Customize returned mimetype

Usage

  1. You can post, update, delete your paste directly on the website (such as shz.al).

  2. It also provides a convenient HTTP API to use. See API reference for details. You can easily call API via command line (using curl or similar tools).

  3. pb is a bash script to make it easier to use on command line.

Limitations

  1. If deployed on Cloudflare Worker free-tier plan, the service allows at most 100,000 reads and 1000 writes, 1000 deletes per day.
  2. Due to the size limit of Cloudflare KV storage, the size of each paste is bounded under 25 MB.

Deploy

You are free to deploy the pastebin on your own domain if you host your domain on Cloudflare.

  1. Install node and yarn.

  2. Create a KV namespace on Cloudflare workers dashboard, remember its ID.

  3. Clone the repository and enter the directory.

  4. Modify entries in wrangler.toml. Its comments will tell you how.

  5. Login to Cloudflare and deploy with the following steps:

$ yarn install
$ yarn wrangler login
$ yarn deploy
  1. Enjoy!

Auth

If you want a private deployment (only you can upload paste, but everyone can read the paste), add the following entry to your wrangler.toml.

[vars.BASIC_AUTH]
user1 = "passwd1"
user2 = "passwd2"

Now every access to POST request, and every access to static pages, requires an HTTP basic auth with the user-password pair listed above. For example:

$ curl example-pb.com
HTTP basic auth is required

$ curl -Fc=@/path/to/file example-pb.com
HTTP basic auth is required

$ curl -u admin1:wrong-passwd -Fc=@/path/to/file example-pb.com
Error 401: incorrect passwd for basic auth

$ curl -u admin1:this-is-passwd-1 -Fc=@/path/to/file example-pb.com
{
  "url": "https://example-pb.com/YCDX",
  "suggestUrl": null,
  "admin": "https://example-pb.com/YCDX:Sij23HwbMjeZwKznY3K5trG8",
  "isPrivate": false
}
