Beginning in the present day, 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 every day, whether or not at work or for private initiatives. They’ll now use Amazon Q Developer for function growth, code evaluations, and Java code migration instantly throughout the GitHub interface.
To show, I’m going to make use of Amazon Q Developer to assist me create an utility from zero referred to as StoryBook Teller. I would like this to be an ASP.Core web site utilizing .NET 9 that takes three photographs 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 the way this works.
Set up
The very first thing it’s essential to do is set up the Amazon Q Developer utility in GitHub, and you may 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 wish to add it to my storybook-teller-demo repo, so I select Solely chosen repositories and kind within the identify to search out it.
That is all it’s essential to do to make the Amazon Q Developer app prepared to make use of inside your chosen repos. You may confirm that the app is put in by navigating to your GitHub account Settings and the app must be listed within the Purposes web page.
You may 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 utility.
Function growth
When Amazon Q Developer is put in right into a repository, you possibly can assign GitHub points to the Amazon Q growth agent to develop options for you. It’s going to then generate code utilizing the entire codebase in your repository as context in addition to the difficulty’s description. That is why it’s necessary to checklist your necessities as precisely and clearly as attainable in your GitHub points, the identical means that you must all the time try 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 venture 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 would like Amazon Q Developer to assist me create the .NET venture. To do that, I open the primary challenge, and within the Labels part, I discover and choose Amazon Q growth agent.
That’s all there’s to it! The problem is now assigned to Amazon Q Developer. After the label is added, the Amazon Q growth agent routinely begins working behind the scenes offering progress updates via the feedback, beginning with one saying, I am engaged on it.
As you may count on, the period of time it takes will rely upon the complexity of the function. When it’s performed, it’ll routinely create a pull request with all of the adjustments.
The subsequent factor I wish to do is make it possible for the generated code works, so I’m going to obtain the code adjustments and run the app regionally on my pc.
I’m going to my terminal and kind 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 venture generated utilizing .NET 9, as I anticipated.
I then run dotnet run and open the app with the URL given within the output.
Good, it really works! Amazon Q Developer took care of implementing this one precisely as I needed primarily based on the necessities I offered within the GitHub challenge. Now that I’ve examined that the app works, I wish 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 performed fairly a little bit of the work for me. Nevertheless, I wish 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 wish to change. I can see that Amazon Q Developer made good assumptions and added exclusion guidelines for Visible Studio (VS) Code information. Nevertheless, JetBrains Rider is my favourite built-in growth surroundings (IDE) for .NET growth, so I wish to add guidelines for it, too.
You may ask Amazon Q Developer to reiterate and make adjustments by utilizing the conventional code assessment movement within the GitHub interface. On this case, I add a remark to the .gitignore code saying, add patterns to disregard Rider IDE information. 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 glad.
Each time Q Developer makes adjustments, it’ll run the automated checks on the generated code. On this case, the code was considerably easy, so it was anticipated that the automated code assessment wouldn’t elevate any points. However what occurs if we’ve got extra complicated code?
Let’s take one other instance and use Amazon Q Developer to implement the function for enabling picture uploads on the web site. I take advantage of the identical movement 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 threat intimately and supplies helpful hyperlinks.
It then routinely generates a prompt code repair.
When it’s performed, you possibly can assessment the code and select to Commit adjustments for those who’re proud of the adjustments.
After fixing this and testing it, I’m proud of the code for this challenge and transfer on making use of the identical course of to different ones. I assign the Amazon Q growth agent to every one among my remaining points, await 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 check my utility on the finish of that software program cycle and am more than happy to see that Amazon Q Developer managed to deal with all points, from venture setup, to boilerplate code, to extra complicated 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 photographs 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 means of figuring out. This highlights the significance of being as exact as attainable in your challenge’s titles and descriptions to offer Q Developer the mandatory context and make the event course of as environment friendly as attainable.
Having mentioned that, it’s nonetheless easy 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 proud of 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
It’s also possible to remodel legacy Java codebases to trendy variations with Q Developer. At the moment, it may well replace functions 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 put up, aside from a couple of issues.
First, it’s essential to create a problem inside a GitHub repository containing a Java 8 or Java 11 utility. The title and outline don’t actually matter on this case. It would even be a brief title resembling “Migration,” leaving the outline empty. Then, on Labels, you assign the Amazon Q remodel agent label to the difficulty.
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, nonetheless, it’s the Amazon Q remodel agent doing the work which is specialised in code migration and can take all the mandatory 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. For those who don’t have it enabled but, it’ll show clear directions that will help you get the whole lot 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 utility.
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. It’s also possible to use it to automate migration from Java 8 and 11 functions to Java 17 making it a lot simpler to get began on that migration venture that you just might need been suspending for some time. Better of all, you are able to do all this from the consolation of your personal GitHub surroundings.
Now accessible
Now you can begin utilizing Amazon Q Developer in the present day at no cost in GitHub, no AWS account setup wanted.
