|

An online tool to convert values between number systems.
|
||||
Quickly convert hexadecimal to binary or base64 to ASCII.
|
||||
Everything happens in the browser, so nothing is submitted to any server.
|
||||
|
||||
## Development
|
||||
### Requirements
|
||||
* [npm](https://www.npmjs.com/)
|
||||
|
||||
### Setting up
|
||||
```shell script
|
||||
# Install dependencies (only needed once)
|
||||
$> npm ci
|
||||
```
|
||||
|
||||
### Building
|
||||
```shell script
|
||||
# Build the tool in `dist/` for development
|
||||
$> npm run dev
|
||||
# Same as above, but automatically rerun it whenever files are changed
|
||||
$> npm run dev:server
|
||||
# Build the tool in `dist/` for deployment
|
||||
$> npm run deploy
|
||||
```
