aws_api for Deno

From-scratch Typescript AWS API client built for Deno.

A leading focus of this library is to be as lean as possible on the number of files downloaded to use a specific service. There’s no single entrypoint; you’ll need to make an ApiFactory and then pass it to the service you want to use.

Package layout:

  • client/: A handwritten generic AWS API client (credentials, signing, etc)
  • encoding/: Shared modules for dealing with XML, JSON, & querystrings
  • services/: Generated Typescript classes and interfaces for all supported AWS services
  • demo.ts: A trivial example of using this library
  • examples/: Several full examples of using individual services
  • SERVICES.md: A complete list of all AWS APIs and their build status

Only some services have completed clients at this time. Please reach out on Github Issues about missing clients or API issues, or ping dantheman#8546 in the Deno Discord if you just wanna chat about this effort.

Usage

Basic example: (see demo.ts for several more services)

import {ApiFactory} from 'https://deno.land/x/aws_api/client/mod.ts';
const factory = new ApiFactory();

import STS from 'https://deno.land/x/aws_api/services/sts@2011-06-15/mod.ts';
const sts = new STS(factory);

const identity = await sts.getCallerIdentity();
console.log('You are', identity.UserId, 'in account', identity.Account);
console.log('Identity ARN:', identity.Arn);

A couple more-detailed examples are in examples/ and show concepts such as managing an EC2 instance’s lifecycle, redriving SQS messages, and working directly with a Kinesis stream.

Disclaimer

This is NOT a port of the official AWS SDK JS. Lots of services are still not bound, and the services that are bound might have issues.

Do not use this module in mission critical stuff. It’s supposed to be for automation scripts, quick & dirty pieces of infrastructure, and prototype microservices and so on.

If you just want the real, full-fat AWS SDK, a port of it has been uploaded at /x/aws_sdk.

Finally, the APIs within client/ and encoding/ are liable to change. For best upgradability, stick to making an ApiFactory object and passing it to the services. At some point (around 1.0.0?) the APIs should be ready to lock in.

Methodology

All of the clients are compiled from aws-sdk-js’s JSON data files. The code to generate clients isn’t uploaded to /x/, so if you want to read through it, make sure you’re in the Git repo.

“Most” of the heavy lifting (such as compiling waiter JMESPaths) runs in the generation step so that the modules on /x/ are ready to run.

Completeness

The following clients have been successfully used in scripts and should work quite well:

  • SQS
  • STS
  • EC2
  • Kinesis

The following credential sources are supported:

  • Environment variables
  • Static credentials in ~/.aws/credentials
  • EKS Pod Identity (web identity token files)

Some individual features that are implemented:

  • Waiters (as .waitForXYZ({...}))
  • Automatic credential loading

Multiple bits are missing:

  • Automatic pagination
  • AssumeRole credentials
  • EC2 instance metadata, and instance credentials
  • Credential chaining
  • Services with REST or XML protocols
  • Debug logging/tracing of API calls
  • Automatic retries
  • AWS endpoints other than **.amazonaws.com (govcloud, China AWS, etc)

List of Typechecked API Clients

All API definitions are current as of aws-sdk-js v2.768.0.
