This code snippet illustrates how a function called addImports can automatically insert missing import statements into JavaScript code, potentially aiding in code completion or refactoring.

Run example

npm run import -- "test add missing imports"

test add missing imports

var importer = require('../Core')
var {addImports} = importer.import("add missing imports")

var code = `
var importer = require('../Core');

addImports('some code')

`

if(typeof $ != 'undefined') {
    $.mime({'text/plain': addImports(code)})
    
    /*
    expected output 
var addImports = importer.import("add missing imports")
*/
    
}

// Import the necessary modules and functions
const { Core, addImports } = require('../Core');

/**
 * The main function that orchestrates the entire process.
 * 
 * @param {string} code - The code to be processed for missing imports.
 * @returns {string} The modified code with missing imports added.
 */
async function processCode(code) {
  try {
    // Get the addImports function from the Core module
    const { addImports } = await import('./Core');

    // Process the code by adding missing imports
    const processedCode = await addImports(code);

    // Return the processed code
    return processedCode;
  } catch (error) {
    // Log any errors that occur during processing
    console.error(error);

    // Return the original code
    return code;
  }
}

/**
 * The main entry point for the script.
 */
async function main() {
  // Define the initial code
  const initialCode = `
var importer = require('../Core');

addImports('some code')
`;

  // Process the initial code
  const processedCode = await processCode(initialCode);

  // Check if the $ object is defined
  if (typeof $!== 'undefined') {
    // Set the MIME type to text/plain
    const mimeType = { 'text/plain': processedCode };

    // Render the processed code
    $({ mimeType });
  }
}

// Run the main function
main();

This code snippet demonstrates a simple example of using a function called addImports to automatically insert missing imports into a JavaScript code snippet.

Here's a breakdown:

1. Importing:

   • It starts by importing the addImports function from a module named Core.

2. Sample Code:

   • Defines a sample JavaScript code snippet (code) that itself imports a function called addImports.

3. Conditional Execution:

   • The code checks if a variable $ exists. This suggests it might be running in a specific environment (like a web browser) where $ is available.

4. Output Generation:

   • If $ exists, it calls addImports on the code snippet and sets the output MIME type to text/plain. This implies the output will be plain text.

5. Expected Output:

   • The comment indicates the expected output, which is the code snippet with the missing import statement for addImports added.

In essence, this code showcases a mechanism for dynamically adding necessary imports to JavaScript code, potentially enhancing code completion or refactoring tools.
