 3[NoPaste](https://nopaste.ml/) is a client-side paste service which works with **no database**, and **no back-end code**
 4
 5Instead, 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]
 6
 7As a result, there is no risk of data being lost, censored or deleted. The data is stored entirely **in the links** and nowhere else!
 8
 9**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...)
10
11## How it works
12
13When you click on "Generate Link", NoPaste compresses the whole text using the
14[LZMA algorithm](https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Markov_chain_algorithm), encodes it in
15[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>`
16
17When you open a link, NoPaste reads, decodes, and decompresses whatever is after the `#`, and displays the result in the editor.
18
19This 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)
20
21## Maximum sizes for links
22
23NoPaste is great for sharing code snippets on various platforms.
24
25These are the maximum link lengths on some apps and browsers.
26
27| App     | Max length |
28| ------- | ---------- |
29| Reddit  | 10,000     |
30| Twitter | 4,088      |
31| Slack   | 4,000      |
32| QR Code | 2,610      |
33| Bitly   | 2,048      |
34
35| Browser         | Max length                | Notes                                   |
36| --------------- | ------------------------- | --------------------------------------- |
37| Google Chrome   | (win) 32,779 (mac) 10,000 | Will not display, but larger links work |
38| Firefox         | >64,000                   |                                         |
39| Microsoft IE 11 | 4,043                     | Will not show more than 2,083           |
40| Microsoft Edge  | 2,083                     | Anything over 2083 will fail            |
41| Android         | 8,192                     |                                         |
42| Safari          | Lots                      |                                         |

44## Embedded NoPaste snippets
45
46You can include NoPaste code snippets into your own website by clicking the _Embed_ button and using the generated HTML code
47
48[This is what an embedded Paste snippet looks like](https://jsfiddle.net/bokub/nwtcdrph/show)
49
50Feel free to edit the generated `height` and `width` attributes, so they suit your needs
51
52## Generate NoPaste links
53
54NoPaste links can be created easily from your system's command line:
55
56```bash
57# Linux
58echo -n 'Hello World' | lzma | base64 | xargs -0 printf "https://nopaste.ml/#%s"
59
60# Mac
61echo -n 'Hello World' | lzma | base64 -w0 | xargs -0 printf "https://nopaste.ml/#%s"
62
63# Windows / WSL
64echo -n 'Hello World' | xz --format=lzma | base64 -w0 | printf "https://nopaste.ml/#%s" "$(cat -)"
65```
