# kweb 2.0.1
KLayout Web Viewer 
Based on https://github.com/klayoutmatthias/canvas2canvas
## Install & Run
### Through pypi
From a python virtual environment run:
```bash
python -m pip install kweb
export KWEB_FILESLOCATION="/path/to/gds/folder" # or the windows equivalent with set
uvicorn --reload kweb.default:app
````
#### Advanced Usage
KWeb offers two basic apps:
- Browser:
A version that provides a version with a file browser for a folder and the kweb viewer for viewing the gds file in that folder.
This can be used by importing the function `kweb.browser.get_app` and settings the `KWEB_FILESLOCATION` env variable of passing
`fileslocation=` to the function. Alternatively there is a default one in `kweb.default.app` that
will only look for the env variable.
- Viewer:
Only enables the `/gds/` endpoints, no root path, i.e. no file browser. Available at `kweb.viewer.get_app`. This version
doesn't provide a listener for the env variable. Use the `fileslocation` parameter in the function instead.
### Development
#### Clone & Installl
```bash
# Clone the repository to your local
git clone https://github.com/gdsfactory/kweb.git
# Install the necessary dependencies
cd /kweb
python -m pip install -e .[dev]
```
#### Set a folder for kweb to use when looking for gds files
```bash
export KWEB_FILESLOCATION=/path/to/folder/with/gdsfiles
```
#### Run
```bash
cd src/kweb
uvicorn --reload default:app
```
Copy the link http://127.0.0.1:8000/gds/file.gds (or http://localhost:8000/gds/file.gds also works) to your browser to open the waveguide example
