Dora Node Hub

This hub contains useful pre-built nodes for Dora.

Structure

The structure of the node hub is as follows (please use the same structure if you need to add a new node):

node-hub/
└── your-node/
    ├── main.py
    ├── README.mdr
    └── pyproject.toml

The idea is to make a pyproject.toml file that will install the required dependencies for the node and attach main
function of the node inside a callable script in your environment.

To do so, you will need to add a main function inside the main.py file.

def main():
    pass

And then you will need to adapt the following pyproject.toml file:

[project]
name = "[name of the node e.g. video-encoder, with '-' to replace spaces]"
version = "0.1"
authors = [{name= "[Pseudo/Name]", email="[email]"]
description = "Dora Node for []"
readme = "README.md"


dependencies = [
"dora-rs = "0.3.5",


... [add your dependencies here] ...
]

[project.scripts]
[name of the node with '-' to replace spaces] = "[name of the node with '_' to replace spaces].main:main"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

Finally, the README.md file should explicit all inputs/outputs of the node and how to configure it in the YAML file.

Example

[project]
name = "opencv-plot"
version = "0.1"
authors = [
    "Haixuan Xavier Tao <tao.xavier@outlook.com>",
    "Enzo Le Van <dev@enzo-le-van.fr>"
]
description = "Dora Node for plotting data with OpenCV"
readme = "README.md"

dependencies = [
    "dora-rs >= 0.3.8",
]
[dependency-groups]
dev = ["pytest >=8.1.1", "ruff >=0.9.1"]

[project.scripts]
opencv-plot = "opencv_plot.main:main"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"
