I’m working on AWS Lambda and I’ve been using the online editor to create my functions. Everything’s been going well so far but now I want to add some extra functionality using external packages like promise libraries.
I’m not sure how to make these packages available to my Lambda functions though. I’ve looked into it a bit and found some info about using EC2 instances or uploading zip files but that doesn’t seem to fit with my current workflow of using the web editor.
Is there an easy way to add packages to my Lambda functions without changing my whole setup? I’m hoping there’s a simple solution that lets me keep working in the online editor but still use external packages. Any advice would be really helpful!
hey there! i’ve been using lambda for a while and ran into this too. one trick i found is using CDK (cloud development kit). it lets u define ur lambda function and dependencies in code, then deploy everything together. its pretty cool cuz u can still use the online editor for quick tweaks. might be worth checkin out!
As someone who’s been working extensively with AWS Lambda, I can tell you that incorporating external packages while using the online editor can be a bit tricky. However, there’s a workaround that might suit your needs.
One approach I’ve found effective is using Lambda Layers. Layers allow you to include libraries and dependencies without modifying your function code. You can create a layer with your desired packages, then attach it to your function directly in the console.
To do this, you’ll need to create the layer separately (usually involving zipping the package and uploading it), but once it’s set up, you can easily add it to your function from the Lambda console. This way, you can continue using the online editor for your main function code while still having access to external packages.
It’s not as straightforward as npm install, but it’s a good compromise that maintains your current workflow. Just be mindful of the total size of your function plus layers, as there are limits to consider.
I’ve encountered a similar challenge with Lambda functions, and I found a solution that might work for you. Instead of using external packages directly, consider using AWS SDK for JavaScript in Node.js. It’s pre-installed in the Lambda environment and offers a wide range of functionalities, including promise support.
For more specific needs, you can inline small libraries or utility functions directly in your Lambda code. This approach keeps everything in the online editor while giving you access to additional capabilities.
If you absolutely need external packages, Lambda Layers is indeed a good option, as mentioned by Samuel87. It’s a bit more complex initially but allows you to keep using the online editor for your main function code.
Remember, Lambda has size limits, so be mindful of how much you’re adding to your function. Always test thoroughly after making changes to ensure everything works as expected in the Lambda environment.
