[![Intro](https://github.com/bokub/nopaste/raw/images/intro.png)][intro-img]

[NoPaste](https://nopaste.ml/) is a client-side paste service which works with **no database**, and **no back-end code**

Instead, the data is **compressed** then **stored** into a unique URL that can be shared and decoded later. For example, [this is the CSS code used by NoPaste][example]

As a result, there is no risk of data being lost, censored or deleted. The data is stored entirely **in the links** and nowhere else!

**Note:** This project is a copy of [Topaz's paste service][topaz-example], with a reworked design and a few additional features (syntax highlighting, line numbers, line wrapping, embedding...)

## How it works

When you click on "Generate Link", NoPaste compresses the whole text using the
[LZMA algorithm](https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm), encodes it in
[Base64](https://en.wikipedia.org/wiki/Base64), and puts it in the optional URL fragment, after the first `#` symbol: `nopaste.ml/#<your data goes here>`

When you open a link, NoPaste reads, decodes, and decompresses whatever is after the `#`, and displays the result in the editor.

This process is done entirely **in your browser**, and the web server hosting NoPaste [never has access to the fragment](https://en.wikipedia.org/wiki/Fragment_identifier)

## Embedded NoPaste snippets

You can include NoPaste code snippets into your own website by clicking the _Embed_ button and using the generated HTML code.

Here is an example of generated code and how it looks (click on the screenshot to see the interactive version)

Feel free to edit the `height` and `width` attributes, so they suit your needs

## Maximum sizes for links

NoPaste is great for sharing code snippets on various platforms.

These are the maximum link lengths on some apps and browsers.

## Generate NoPaste links

NoPaste links can be created easily from your system's command line:

```bash
# Linux
echo -n 'Hello World' | lzma | base64 | xargs -0 printf "https://nopaste.ml/#%s"

# Mac
echo -n 'Hello World' | lzma | base64 -w0 | xargs -0 printf "https://nopaste.ml/#%s"

# Windows / WSL
echo -n 'Hello World' | xz --format=lzma | base64 -w0 | printf "https://nopaste.ml/#%s" "$(cat -)"
```
