Description
node-python
is a wrapper for Node.js that enables interactive communication with the Python shell. It simplifies the process of starting and communicating with Python child processes, making it easier to integrate Python functionality into Node.js projects.
Example
To use node-python
in a project, first install it using npm:
npm install python
Now, let’s see how to use it to start a Python child process, read input from stdin, pipe it to the Python shell, and run a callback method with the resulting output.
// app.js
const python = require('python').shell;
const mycallback = function(err, data) {
if (err) {
console.error(err);
} else {
console.log("Callback function got: ", data);
}
};
process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin.on('data', function(chunk) {
python(chunk, mycallback);
});
In this example, we import the python
module and define a callback function mycallback
to handle the response. We then set up the Node.js process to read input from stdin and pipe it to the Python shell using the python
function. The state is preserved in the shell between calls.
Why it’s used with docker/genai-stack
node-python
is used in the context of docker/genai-stack
when you need to interact with Python-based tools or scripts from within a Node.js application. It simplifies the process of starting and communicating with Python child processes, making it easier to integrate Python functionality into your Node.js projects.
