Beginning as we speak, now you can use Amazon Q Developer in GitHub in preview! That is implausible information for the tens of millions of builders who use GitHub each day, whether or not at work or for private initiatives. They’ll now use Amazon Q Developer for characteristic improvement, code opinions, and Java code migration immediately inside the GitHub interface.
To reveal, I’m going to make use of Amazon Q Developer to assist me create an software from zero known as StoryBook Teller. I need this to be an ASP.Core web site utilizing .NET 9 that takes three pictures from the consumer and makes use of Amazon Bedrock with Anthropic’s Claude to generate a narrative primarily based on them.
Let me present you ways this works.
Set up
The very first thing you want to do is set up the Amazon Q Developer software in GitHub, and you’ll start utilizing it instantly with out connecting to an AWS account.
You’ll then be introduced with a selection so as to add it to all of your repositories or choose particular ones. On this case, I need to add it to my storybook-teller-demo repo, so I select Solely chosen repositories and sort within the identify to seek out it.
That is all you want to do to make the Amazon Q Developer app prepared to make use of inside your chosen repos. You possibly can confirm that the app is put in by navigating to your GitHub account Settings and the app ought to be listed within the Functions web page.
You possibly can select Configure to view permissions and add Amazon Q Developer to repositories or take away it at any time.
Now let’s use Amazon Q Developer to assist us construct our software.
Characteristic improvement
When Amazon Q Developer is put in right into a repository, you possibly can assign GitHub points to the Amazon Q improvement agent to develop options for you. It would then generate code utilizing the entire codebase in your repository as context in addition to the problem’s description. For this reason it’s essential to listing your necessities as precisely and clearly as potential in your GitHub points, the identical approach that it’s best to at all times attempt for anyway.
I’ve created 5 points in my StoryBook Teller repository that cowl all my necessities for this app, from making a skeleton .NET 9 challenge to implementing frontend and backend.
Let’s use Amazon Q Developer to develop the appliance from scratch and assist us implement all these options!
To start with, I need Amazon Q Developer to assist me create the .NET challenge. To do that, I open the primary difficulty, and within the Labels part, I discover and choose Amazon Q improvement agent.
That’s all there may be to it! The problem is now assigned to Amazon Q Developer. After the label is added, the Amazon Q improvement agent mechanically begins working behind the scenes offering progress updates by means of the feedback, beginning with one saying, I am engaged on it.
As you may count on, the period of time it takes will depend upon the complexity of the characteristic. When it’s completed, it would mechanically create a pull request with all of the adjustments.
The following factor I need to do is ensure that the generated code works, so I’m going to obtain the code adjustments and run the app domestically on my pc.
I’m going to my terminal and sort git fetch origin pull/6/head:pr-6 to get the code for the pull request it created. I double-check the contents and I can see that I do certainly have an ASP.Core challenge generated utilizing .NET 9, as I anticipated.
I then run dotnet run and open the app with the URL given within the output.
Sensible, it really works! Amazon Q Developer took care of implementing this one precisely as I needed primarily based on the necessities I supplied within the GitHub difficulty. Now that I’ve examined that the app works, I need to assessment the code itself earlier than I settle for the adjustments.
Code assessment
I’m going again to GitHub and open the pull request. I instantly discover that Amazon Q Developer has carried out some computerized checks on the generated code.
That is nice! It has already completed fairly a little bit of the work for me. Nevertheless, I need to assessment it earlier than I merge the pull request. To try this, I navigate to the Recordsdata modified tab.
I assessment the code, and I like what I see! Nevertheless, trying on the contents of .gitignore, I discover one thing that I need to change. I can see that Amazon Q Developer made good assumptions and added exclusion guidelines for Visible Studio (VS) Code recordsdata. Nevertheless, JetBrains Rider is my favourite built-in improvement setting (IDE) for .NET improvement, so I need to add guidelines for it, too.
You possibly can ask Amazon Q Developer to reiterate and make adjustments by utilizing the traditional code assessment circulate within the GitHub interface. On this case, I add a remark to the .gitignore code saying, add patterns to disregard Rider IDE recordsdata. I then select Begin a assessment, which is able to queue the change within the assessment.
I choose End your assessment and Request adjustments.
Quickly after I submit the assessment, I’m redirected to the Dialog tab. Amazon Q Developer begins engaged on it, resuming the identical suggestions loop and inspiring me to proceed with the assessment course of till I’m happy.
Each time Q Developer makes adjustments, it would run the automated checks on the generated code. On this case, the code was considerably simple, so it was anticipated that the automated code assessment wouldn’t elevate any points. However what occurs if now we have extra advanced code?
Let’s take one other instance and use Amazon Q Developer to implement the characteristic for enabling picture uploads on the web site. I exploit the identical circulate I described within the earlier part. Nevertheless, I discover that the automated checks on the pull request flagged a warning this time, stating that the API generated to help picture uploads on the backend is lacking authorization checks successfully permitting direct public entry. It explains the safety danger intimately and supplies helpful hyperlinks.
It then mechanically generates a prompt code repair.
When it’s completed, you possibly can assessment the code and select to Commit adjustments when you’re pleased with the adjustments.
After fixing this and testing it, I’m pleased with the code for this difficulty and transfer on making use of the identical course of to different ones. I assign the Amazon Q improvement agent to every one among my remaining points, watch for it to generate the code, and undergo the iterative assessment course of asking it to repair any points for me alongside the way in which. I then take a look at my software on the finish of that software program cycle and am very happy to see that Amazon Q Developer managed to deal with all points, from challenge setup, to boilerplate code, to extra advanced backend and frontend. A real full-stack developer!
I did discover some issues that I needed to alter alongside the way in which. For instance, it defaulted to utilizing the Invoke API to ship the uploaded pictures to Amazon Bedrock as a substitute of the Converse API. Nevertheless, as a result of I didn’t state this in my necessities, it had no approach of figuring out. This highlights the significance of being as exact as potential in your difficulty’s titles and descriptions to provide Q Developer the required context and make the event course of as environment friendly as potential.
Having mentioned that, it’s nonetheless simple to assessment the generated code on the pull requests, add feedback, and let the Amazon Q Developer agent hold engaged on adjustments till you’re pleased with the ultimate end result. Alternatively, you possibly can settle for the adjustments within the pull request and create separate points which you could assign to Q Developer later whenever you’re able to develop them.
Code transformation
You may also rework legacy Java codebases to trendy variations with Q Developer. At the moment, it might probably replace purposes from Java 8 or Java 11 to Java 17, with extra choices coming in future releases.
The method is similar to the one I demonstrated earlier on this publish, apart from just a few issues.
First, you want to create a difficulty inside a GitHub repository containing a Java 8 or Java 11 software. The title and outline don’t actually matter on this case. It would even be a brief title akin to “Migration,” leaving the outline empty. Then, on Labels, you assign the Amazon Q rework agent label to the problem.
Very like earlier than, Amazon Q Developer will begin working instantly behind the scenes earlier than producing the code on a pull request which you could assessment. This time, nevertheless, it’s the Amazon Q rework agent doing the work which is specialised in code migration and can take all the required steps to research and migrate the code from Java 8 to Java 17.
Discover that it additionally wants a workflow to be created, as per the documentation. If you happen to don’t have it enabled but, it would show clear directions that will help you get all the pieces arrange earlier than making an attempt once more.
As anticipated, the period of time wanted to carry out a migration relies on the scale and complexity of your software.
Conclusion
Utilizing Amazon Q Developer in GitHub is like having a full-stack developer which you could collaborate with to develop new options, speed up the code assessment course of, and depend on to boost the safety posture and high quality of your code. You may also use it to automate migration from Java 8 and 11 purposes to Java 17 making it a lot simpler to get began on that migration challenge that you simply may need been suspending for some time. Better of all, you are able to do all this from the consolation of your individual GitHub setting.
Now out there
Now you can begin utilizing Amazon Q Developer as we speak at no cost in GitHub, no AWS account setup wanted.
Amazon Q Developer in GitHub is presently in preview.
