[Tables] Create clients from connectionString #10292

joheredi · 2020-07-27T01:52:27Z

Support 2 kinds of connection strings to instantiate TableClient and TableServiceClient

Account Connection String (Node.js Only)
SAS Connection String

Docs for Tables Shared Key Authorization: https://docs.microsoft.com/en-us/rest/api/storageservices/authorize-with-shared-key#table-service-shared-key-authorization

Note: Parts of the authorization using Shared Keys are similar to other Storage Services, however Tables has some specific requirements different from Blob, Queues, etc. It may be a good idea at some point to move common building blocks to a common/core package so that each service can compose their own Authorization reusing them. Filed issue #10291 to track this investigation

This is only in Node.JS today because of the dependency on HMAC? We've been making a push in other libraries to be able to do this HMAC stuff in browser as well (I know Richard recently did some work in the Application Configuration SDK to support this). I'm looking at trying to get us a @azure/core-crypto library that will expose some of these primitives in a way that would work in node or browsers, so I'd like to know what all is keeping this node today, so we can expose the right set of primitives so we can have code like this work in the browser as well.

If we had support for doing SHA265 HMAC would that be sufficient to get us browser support here?

Yeah, I think that's the only thing holding us back in this case

I asked @XiaoningLiu before for other storage libraries. I remember there are more reasons than hmac support for not having connection strings/shared key credential for browsers. Maybe security related. @XiaoningLiu can you confirm?

Yes. It's security concern. SharedKey in browser session is almost public. Storage team recommends using SAS or OAuth in browser sessions.

Thanks @jeremymeng for bringing this up. @XiaoningLiu do you have a doc reference about the security issue, that I can include in the comments of this file to make sure people are aware why this is not supported in the Browser?

The SharedKeyCredential has complete access to your account. Putting it in the hands of clients means clients now have the power to do anything including delete all your data, and moreover, other (possibly untrusted 3rd party) code running in the application can exfiltrate the key trivially. Maybe a vague "for security reasons" is sufficient?

sdk/tables/azure-tables/src/utils/connectionString.ts

+import { URL } from "./url";
+
+export interface ConnectionString {
+  kind: "AccountConnString" | "SASConnString";


Do these strings have some sort of well understood meaning? Would AccountConnectionString and SASConnectionString work better (or alternately since this is already on the ConnectionString interface, just Account and SAS)

I see that this doesn't end up getting exported from index.ts, so I'm less concerned about this.

This is only used to distinguish the connection strings internally, not for the users :)

Can you help me understand why this change happened here? I'm especially interested in the dom addition (and also I don't really understand why we would have libs for es5, es6, es7 and esnext. Shouldn't we pick a specific one (and have it be the oldest one we can use)?

dom as added to include DOM declarations and be able to work with URL in url.browser.ts. The others are not needed so I'm going to remove them.

Of course, that makes sense. Forgot about the special handing around URL.

Unnecessary to disable/enable PR triggers in your fork, the trigger rules are actually controlled by the target branch anyway, so I suspect this didn't have an impact ;)

This did disable js - tables - ci in PR validation. See this PR #10207 which still has this commented out it doesn't trigger js - tables - ci

Should we require @azure/tables in here and samples/typescript/package.json?

Yeah, I wasn't adding it because the package is not yet published. However it looks like we can add it here with a local reference. I'll do that 😄 once we publish we can start grabbing it from NPM
