kandi X-RAY | amazon-cognito-js Summary
The Cognito Sync Manager for JavaScript allows your web application to store data in the cloud for your users and synchronize across other devices. The library uses the browser’s local storage API to create a local cache for the data, similar to our [mobile SDK] This allows your web application to access stored data even when there is no connectivity. Note: This library is designed to run in the browser. It has not been tested for use in other environments.

QUESTION
As of now, there are at least 5 packages for the AWS SDK as it pertains to Cognito.
- Custom built via multiple mechanisms: https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/building-sdk-for-browsers.html
- https://github.com/aws/amazon-cognito-identity-js
- https://github.com/aws/amazon-cognito-auth-js
- https://github.com/aws/amazon-cognito-js
The global SDK https://github.com/aws/aws-sdk-js
Some of them overlap in terms of methods. Many are only slightly different. The docs and links vary from outdated to flat out incorrect.
Most docs are in ES5, some in ES6, some in TypeScript, some in Node.
How are developers supposed to know how to make heads or tails from these?
...ANSWER
Answered 2017-Oct-09 at 19:04I work with Cognito everyday as a developer. I recommend starting with the AWS JavaScript SDK (the full SDK). Everything that you need for Cognito development is there and is always the latest. Once you know the details for Cognito, take a look at the higher level packages. By that time you will probably have written your own library of code and then won't consider the others.
The problem with Cognito development is that unless you stay with the core SDK, the other packages either don't exist or are not compatible with SDKs for other platforms or for other languages such as PHP or Java.
Depending on your goals / requirements, you may need to support mobile, desktop, server, Lambda, etc. If you stay with the core SDK then you can quickly adapt to each environment. If you use a higher level package that only works, for example with node.js, then you have a porting problem.
[EDIT]
One item that I forgot to mention is that Cognito is really three different services and therefore three different sections (classes, etc.) within the SDK. There is Cognito User Pools, Cognito Federated Identities and Cognito Sync. Some of the higher level SDKs only support one or the other or just parts of one to make interfaces easier (or more intuitive).
