AWS provides aws-sdk npm package to work with AWS services. Below function updateCloudfrontTTL() updates the MaxTTL value of default behavior to 0.
const AWS = require("aws-sdk");
async function updateCloudfrontTTL(distributionId) {
const cf = new AWS.CloudFront();
const params = await cf
.getDistributionConfig({ Id: distributionId })
.promise();
params.IfMatch = params.ETag;
delete params.ETag;
params.Id = distributionId;
params.DistributionConfig.DefaultCacheBehavior.MaxTTL = 0;
const res = await cf.updateDistribution(params).promise();
return {
id: res.Distribution.Id,
arn: res.Distribution.ARN,
url: `https://${res.Distribution.DomainName}`,
};
}Line 4: Create CloudFront object
Line 6: Get the current configuration of a distribution
Line 10: Set current ETag value to IfMatch. This step is mandatory.
Line 16: Set MaxTTL to 0. In similar manner you can update whatever you want.
Line 18: Finally, invoke updateDistribution() method to actually update the settings in AWS.
Line 20 - 23: shows how to read values from the response object.
