To use a persistent token across restarts, set the `JWT_SECRET` environment variable before starting the server.\n\n### 2.

Persistent token (optional)\n\nBy default, a new token is generated on every restart, which will invalidate any active sessions. To keep sessions alive across restarts, set a fixed secret before starting the server:\n\n```sh\nexport ZASPER_JWT_SECRET=your-secret-here\nzasper --protected=true\n```\n\n## Jupyter kernels\n\nPlease ensure you have jupyter kernels installed.\n\n```\nprasunanand@Prasuns-Laptop examples % jupyter kernelspec list\nAvailable kernels:\n  deno          \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Fdeno\n  firstenv      \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Ffirstenv\n  gonb          \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Fgonb\n  ir            \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Fir\n  julia-1.11    \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Fjulia-1.11\n  ruby3         \u002FUsers\u002Fprasunanand\u002FLibrary\u002FJupyter\u002Fkernels\u002Fruby3\n  python3       \u002FUsers\u002Fprasunanand\u002FLibrary\u002FPython\u002F3.9\u002Fshare\u002Fjupyter\u002Fkernels\u002Fpython3\n```\nThe simplest way to install a Python 3 Jupyter kernel is\n\n```\npip install ipykernel\n```\n\nor\n\n```\npip install jupyter\n```\n\n## Working with conda environments\n\nCreate an environment.\n```\nconda create --name torchEnv\n```\n\nActivate the environment.\n```\nconda activate torchEnv\n```\n\nInstall the necessary packages and ipykernel\n\n```\nconda install -c anaconda ipykernel\n```\n\nCreate `kernelspec` file and you are done! 🚀\n\n```\npython -m ipykernel install --user --name=torchEnv\n```\n\n## Working with UV\n\nCreate a project.\n```\nuv init exampleUV\ncd exampleUV\nuv run main.py    # This creates a .venv directory\n```\n\nActivate the environment.\n```\n\nsource .venv\u002Fbin\u002Factivate\n```\n\nInstall the necessary packages and ipykernel\n\n```\nuv pip install ipykernel\n```\n\nCreate `kernelspec` file and you are done! 🚀\n\n```\nuv run python -m ipykernel install --user --name=exampleUV\n```\n\n## ⚡️ Building from Source\n\n#### Initializing\n\nDownload `zasper` from Github and initialize the dependencies.\n\n```\ngit clone https:\u002F\u002Fgithub.com\u002Fzasper-io\u002Fzasper\ncd zasper\nmake init\n```\n\n#### Web App\n\n```\nmake webapp-install\n```\n\nThis will create a binary `zasper` and add it to your go executables directory.
