cloudwatch-public-metrics's Issues

Update lambda runtime to latest LTS

Fix lambda permissions

After deploying function to AWS, seems like Lambda has incorrect IAM policies attached:

AccessDenied: User: arn:aws:sts::085108115628:assumed-role/lambda-dashboard-dev-us-east-1-lambdaRole/lambda-dashboard-dev-main is not authorized to perform: cloudwatch:GetMetricStatistics

Change line interpolation method

Due to current interpolation method some values are represented inaccurately.

Add ability to expose multiple metrics at once

As title says. Building simple dashboards should be also possible.

I have a notion that it would require change the way how config is passed to lambda function. Instead of using env variables which are a bit primitive, config should be hardcoded before deployment and expressed in .js file?

Support using `--flags` as configuration option

Instead of using config.yml it should be possible to specify cfg values using flags with npm run deploy command.

Add rate limiting

To prevent DDoS attacks, it should be possible to config rate limiting. It is possible to setup it inside API Gateway options but does Serverless framework supports that? Need to check.

Decrease artifact size

Right now service zip file is 17.25 MB which is definitely too big for such simple app.

Add interactivity to chart

Right now whole page is 100% static and does not allow any interactions.

Question: Do you believe that adding interactions to chart would be beneficial?

Add npx integration

It should be possible to provision whole page using one npx-based command.

Something like:

npmx cloudwatch-public-metrics \
  --metricName AWS/Billing//EstimatedCharges \
  --metricDuration 15days \
  and so on..

Blocked by: #4

Add eslint setup

To prevent basic bugs and enforce consistent codestyle, eslint should be added.
