The code imports modules from the Core module using the require function and an importer object, and then uses the imported functions to create a JSON object and perform logging and interface output. The JSON object is created using the wireJson function and contains properties such as display_name, argv, and language, which are then logged to the console along with the result of an interface function call.

Run example

npm run import -- "test notebook kernel json"

test notebook kernel json

var importer = require('../Core');
var interface = importer.import("enforcing an interface");
var {wireJson, jsonInterface} = importer.import("notebook kernel json");

var json = wireJson({
    display_name: 'Node JS',
    argv: [],
    language: '',
    some_other_stuff: true
});
console.log(JSON.stringify({
    argv: json.argv,
    display_name: json.display_name,
    language: json.language,
}))
console.log(interface(json, jsonInterface));

/* output like 
{ argv:
   [ 'npm',
     'run',
     'import',
     '--',
     'get javascript kernel',
     '["{connection_file}"]' ] }
*/

// Import required modules and interfaces
const { wireJson, jsonInterface } = require('../Core').import({
  'enforcing an interface': 'interface',
  'notebook kernel json': ['wireJson', 'jsonInterface']
});

// Define the JSON data to be parsed
const jsonData = {
  display_name: 'Node JS',
  argv: [],
  language: '',
  some_other_stuff: true
};

// Convert the JSON data into a usable format
const parsedJson = wireJson(jsonData);

// Log the argv and display_name properties of the parsed JSON
console.log(`argv: ${parsedJson.argv}`);
console.log(`display_name: ${parsedJson.display_name}`);

// Log the interface results
console.log(interface(parsedJson, jsonInterface));

// TODO: Implement further validation and error handling for the imported modules and interfaces

Code Breakdown

Importing Modules

var importer = require('../Core');
var interface = importer.import('enforcing an interface');
var {wireJson, jsonInterface} = importer.import('notebook kernel json');

• The require function is used to import the Core module from a relative path.
• The importer object has two methods called import which are used to import specific modules named 'enforcing an interface' and 'notebook kernel json' from the Core module.
• The importer.import method returns the imported modules or specific functions from the imported modules, respectively.
• The interface variable holds the entire 'enforcing an interface' module.
• The {wireJson, jsonInterface} destructures the imported 'notebook kernel json' module, assigning the wireJson and jsonInterface functions to separate variables.

Creating JSON Object

var json = wireJson({
    display_name: 'Node JS',
    argv: [],
    language: '',
    some_other_stuff: true
});

• The wireJson function is used to create a JSON object.
• The JSON object contains properties:
  • display_name with value 'Node JS'.
  • argv with an empty array [].
  • language with an empty string ''.
  • some_other_stuff with boolean value true.

Logging JSON Object and Interface Output

console.log(JSON.stringify({
    argv: json.argv,
    display_name: json.display_name,
    language: json.language,
}))
console.log(interface(json, jsonInterface));

• The JSON.stringify method is used to convert the JSON object into a string.
• The string is logged to the console with properties argv, display_name, and language.
• The interface function is called with the json object and jsonInterface as arguments, and the result is logged to the console.
• The interface function takes two arguments: a JSON object and an interface description. It is likely used to validate or transform the JSON object according to the interface description.
