How to make redirect using Lambda@Edge?

This instruction will help you to make 301 redirect using CloudFront(CF) and Lambda@Edge.

exports.handler = (event, context, callback) => {
    const request = event.Records[0].cf.request;
    const uri = request.uri;

    if (uri === "/some-url-you-want-to-redirect/") {
        const response = {
            status: '301',
            statusDescription: 'Permanently Moved',
            headers: {
                location: [{
                    key: 'Location',
                    value: 'https://site.com/url-for-redirection'
                }]
        }}
        callback(null, response);
    } else {
        callback(null, request)
    }
};

1. Create the function using Lambda Functions of AWS
