This code performs a web search using a custom search engine and sends the results (or any errors) to an external system for further processing. It uses promises to handle the asynchronous nature of the search operation.
npm run import -- "test custom search"
var importer = require('../Core');
var search = importer.import("search the web");
$.async();
search('google')
.then(({items}) => $.sendResult(items))
.catch(e => $.sendError(e))
// Import the core module and search function
const { importer } = require('../Core');
const { search } = importer.import('search the web');
// Run the asynchronous function
async function runSearch(query) {
try {
// Search the web for the given query
const result = await search(query);
return result.items;
} catch (error) {
// Handle any errors that occur during the search process
throw error;
}
}
// Run the search function
const query = 'google';
runSearch(query)
.then(items => $.sendResult(items))
.catch(e => $.sendError(e));
```
Or using async/await syntax for better readability:
```javascript
// Import the core module and search function
const { importer } = require('../Core');
const { search } = importer.import('search the web');
// Run the asynchronous function
async function main() {
try {
// Run the search function
const query = 'google';
const items = await search(query);
// Send the result
$.sendResult(items);
} catch (error) {
// Send the error
$.sendError(error);
}
}
// Run the main function
main();
This code snippet performs a web search using a custom search engine and sends the results to an external system.
Here's a breakdown:
Dependencies: It imports a function search
from a local module Core
which likely handles the interaction with a web search engine.
Execution:
$.async()
.search
function with the query "google"..then()
block handles the successful search result, extracting the items
array (presumably containing search results) and sending it to the external system using $.sendResult
..catch()
block handles any errors during the search process and sends the error to the external system using $.sendError
.
