What?

A proof-of-concept simple key value store using the serverless platform webtask.io.

Why?

I was interested in learning more about the serverless platform webtask.io. I was also tasked with hacking together something using webtask.io and felt I should build something that myself or someone else would find useful for future projects.

I've found that a simple key value store is something I really need for hacking on tiny proof of concept projects which require very little state. Hacking together a key value store on webtask.io was perfect for this.

How?

First, install the wt command line interface:

    # npm install wt-cli -g

Initialize wt:

    $ wt init $EMAIL

Then deploy:

    $ bash deploy.sh s3cr3t

This will create a webtask using webtask.js named kv-poc. You will need the authorization secret s3cr3t to access the webtask. deploy.sh will output the URL for the webtask.

To POST key values:

    $ curl -H "Authorization: Bearer s3cr3t" -X POST $WEBTASK_URL \
      -d "key=Australia" -d "value=AUD"

    $ curl -H "Authorization: Bearer s3cr3t" -X POST $WEBTASK_URL \
      -d "key=Greece" -d "value=EUR"

    $ curl -H "Authorization: Bearer s3cr3t" -X POST $WEBTASK_URL \
      -d "key=China" -d "value=CNY"

To GET a value from a specific key:

    $ curl -H "Authorization: Bearer s3cr3t" $WEBTASK_URL/Australia

To GET all key values:

    $ curl -H "Authorization: Bearer s3cr3t" $WEBTASK_URL

To DELETE a key value:

    $ curl -H "Authorization: Bearer s3cr3t" -X DELETE $WEBTASK_URL/Australia

For a simple test suite, I wrote test.sh:

    $ bash test.sh
