util-encoding

This example showcases some of the basic data encoding utils in quais. It is comprised of 3 example scripts:

• base58.js - base58 encoding utils
• base64.js - base64 encoding utils
• rlp.js - RLP encoding utils

Dependencies

• Node.js - JavaScript runtime
• quais - Quai JavaScript SDK

Usage

To install dependencies, navigate to this directory (quais-by-example/util-encoding) and run:

npm install

Use nodejs to run any of the scripts in this example. For example:

node base58.js

Example Breakdown

base58.js

This script takes an initial string, decodes it to a Uint8Array, and then encodes it back to a string using base58. To run the script, you'll need to edit the toDecode variable:

const toDecode = 'hello world'

Once you've done that, you can run the script with:

node base58.js

The script will output the decoded and encoded strings.

base64.js

This script takes an initial string, decodes it to a Uint8Array, and then encodes it back to a string using base64. To run the script, you'll need to edit the toDecode variable:

const toDecode = 'base64 encoding is fun!'

Once you've done that, you can run the script with:

node base64.js

The script will output the decoded and encoded strings.

rlp.js

This script takes an initial hex-string, encodes it using RLP encoding, and then decodes it back to a hex-string. To run the script, you'll need to edit the toEncode variable:

const toEncode = '0x1234'

Once you've done that, you can run the script with:

node rlp.js

The script will output the encoded and decoded hex-strings.
