@leo-buneev thanks for the good work on this. It seems like PR is stuck in the review process. Can you please rebase the branch again so someone from the core team can review and merge it. I can really use the Azure function support in Apollo Server.

[leo-buneev]

@hsdhillon Sure, will do tomorrow.

[abernix]

A couple changes, but I think we can get this into an alpha release! @michaelwatson93 went ahead and applied the appropriate updates from the master branch (since many changes are not easily or intuitively mergeable) and I've followed up with a couple changes to the package-lock.json and README.md/CHANGELOG.md.

[abernix]

It'd be great if we could include these definitions from somewhere else!

[leo-buneev]

I've tried to use existing external definitions, but they were incomplete/outdated.
Do you think I should publish typings as a separate package?

[abernix]

Published as apollo-server-azure-function@2.2.0-alpha.4.

[abernix]

Thank you so much for working on this @leo-buneev!

(And thanks to @michael-watson for wrapping it up!)

[hsdhillon]

Thanks for your work @leo-buneev and thanks to @abernix for merging and publishing the package.

I quickly wanted to point out that package is published as apollo-server-azure-function whereas the documentation refers to package name with "s" at the end. apollo-server-azure-functions points to package with 1.x release. Attached screenshot shows the search result on npmjs

[leo-buneev]

I'm happy to help. @abernix @michaelwatson93 thank you for wrapping it up and merging!

[divyenduz]

@leo-buneev : Thanks for the awesome work 🙌

When will this be available to use? Also, I saw that the name is apollo-server-azure-function at some places and apollo-server-azure-functions at some places, in fact, only yesterday, I got a PR merged that has different name than this PR: https://github.com/apollographql/apollo-server/pull/1938/files

Can you please help me with this 🙂

[divyenduz]

Published as apollo-server-azure-function@2.2.0-alpha.4.

I think this is apollo-server-azure-functions@2.2.0-alpha.4. Can you please confirm? @abernix

[divyenduz]

I am unable to get this to work, I get a blank screen at the moment. Here is a reproduction: https://github.com/divyenduz/apoll-server-azure-function

[divyenduz]

Ah! this worked, after using $return as mentioned here: https://github.com/apollographql/apollo-server/pull/1753/files#diff-efb81a2b2121744f5c5529cf58a2f1d7R67

[abernix]

Glad you got it working @divyenduz ! Maybe we should make that portion more clear in the documentation.
