Fitness Tracker

This serverless app combined with express is designed to pull information from a Google Fit API and present it either directly or via an aggregator to my personal projects.

Usage

Deployment

Install dependencies with:

npm install

and then deploy with:

serverless deploy

After running deploy, you should see output similar to:

Deploying fitness-tracker to stage dev (us-east-1)

✔ Service deployed to stack fitness-tracker-dev (196s)

endpoint: ANY - https://xxxxxxxxxx.execute-api.us-east-1.amazonaws.com
functions:
  api: fitness-tracker-dev-api (766 kB)

Note: In current form, after deployment, your API is public and can be invoked by anyone. For production deployments, you might want to configure an authorizer. For details on how to do that, refer to httpApi event docs.

Invocation

After successful deployment, you can call the created application via HTTP:

curl https://xxxxxxx.execute-api.us-east-1.amazonaws.com/

Which should result in the following response:

{"message":"Hello from root!"}

Calling the /hello path with:

curl https://xxxxxxx.execute-api.us-east-1.amazonaws.com/hello

Should result in the following response:

{"message":"Hello from path!"}

If you try to invoke a path or method that does not have a configured handler, e.g. with:

curl https://xxxxxxx.execute-api.us-east-1.amazonaws.com/nonexistent

You should receive the following response:

{"error":"Not Found"}

Local development

It is also possible to emulate API Gateway and Lambda locally by using serverless-offline plugin. In order to do that, execute the following command:

serverless plugin install -n serverless-offline

It will add the serverless-offline plugin to devDependencies in package.json file as well as will add it to plugins in serverless.yml.

After installation, you can start local emulation with:

serverless offline

To learn more about the capabilities of serverless-offline, please refer to its GitHub repository.
