In part 2 we will cover the steps after you have done your coding; testing and debugging.. mynamespace.model. A service is what you might call a Serverless project. The term “serverless” refers to how the application is executed, whereas the term “microservices” refers to the internal structure of the application. Per Serverless Framework specifications, every serverless project should have serverless.yml at the project root location. Basically, the project structure for a Node.js based Serverless application looks like this: src/ index.js service.js package.json package-lock.json src/tests/unit/ tests.js src/tests/integration/ tests.js sam-template.yaml The index.js contains all the handlers for the different Lambda functions comprising a … Project Structure. Removes deployed functions from your AWS account based on the provided stage/region. Microservices can grow out of control and each added service increases the complexity of your application. The monolith pattern involves taking advantage of API Gateway’s {proxy+} and ANY method to route all the requests to a single Lambda function. First let’s start by quickly looking at the common terms used when talking about Serverless Framework projects. We do, however, recommend using the api directory to keep things simple for your project. Most of the code changes are going to happen in the serverless-stack-demo-ext-api repo.
