faasd VS serverless-offline

If you don't want to start with Kubernetes, faasd (https://github.com/openfaas/faasd) might be worth a look.

I found OpenFaaS and its little sibling faasd. To my understanding they expose single functions through a REST API for easy interfacing. It sounds nice but OpenFaaS is overkill and I had trouble setting up faasd.

Hope you find this interesting / useful - whether you're using AWS Lambda, OpenFaaS, or just plain old Go binaries. If you're wondering whether OpenFaaS requires K8s, you also have faasd as an option.

Have you seen faasd from openfaas? Easier to setup and doesn‘t require a full blown kubernetes cluster: https://github.com/openfaas/faasd

I'm the original creator of faasd, and just found this post on the Internet. What I liked was how he discovered faasd and found some unique value in it.

I wanted to share it all with a broader audience here. His bootstrap is a little bit convoluted, if you check out GitHub, we have a simple installer script and an eBook as a reference manual.

First of all, you need faas-cli in your client local machine. You should get the binary and set it to your path. If you are on linux or mac machine, moving the binary into "/usr/local/bin" will work. For windows machines, you need to set environment variables in Control Panel>System and Security>System>Advanced System Settings(single-binary-faas-cli)

Have you considered OpenFaaS - https://github.com/openfaas/faasd

I am on the same ship, after some digging around I'm considering OpenFaaS, checkout - https://github.com/openfaas/faasd

If you use https://github.com/openfaas/faasd, you can skip the whole Kubernetes setup as well.

Using local emulators like sam local, serverless-offline, localstack, etc.

Hi, I'm the creator of serverless-offline (https://github.com/dherault/serverless-offline), a NPM package for local serveless development on AWS.

I'm building a cool product and intend to launch Q1 2023. To gain traction from my target customers, I plan to place a discrete ad at the launch of every serverless-offline instance.

Does it seem like an ok move to you? Or is it something that repels you?

Best,

As the creator of serverless-offline, I am well placed to tell you that this is the time-effective solution. Plus, it costs way less than other solutions at smaller scales. But, again, going Kubernetes or otherwise will be a problem for the future.

What if I didn’t need to push code to AWS every time I wanted to test something? All heroes don’t wear capes. Like a knight in shining armor, Serverless Offline comes barging in to save the day! At least now I can test all my code locally before pushing it to AWS. That’s a relief.

With classic Express servers, you can use a simple node script to get the server up and running to test locally. Serverless wants to be run in the AWS ecosystem making it. Lucky for us, David Hérault has built and continues to maintain serverless-offline allowing us to emulate our functions locally before we deploy.

With the serverless offline plugin you can speed up local dev is by emulating AWS lambda and API Gateway locally when developing your Serverless project.

Those mocks are by definition not real services so there are some behavior differences between the local environment and the cloud provider. For example, AWS API Gateway emulated by serverless-offline doesn't handle VTL locally the same as AWS does.

serverless-offline (https://github.com/dherault/serverless-offline) is a great tool to use for local development of serverless applications.

It's not a complete mirror image of what you get but it's close enough in my experience.
