Version pinning

If you want to install and pin a specific version of memo, you can do so by referencing a specific release tarball.

An example with npm;

npm install https://github.com/oghdev/memo/archive/0.1.0.tar.gz

Usage

Using the Node API

You can also use memo via an exposed api:

$ cat listen.js

const Memo = require('memo')

const host = process.env.ACTIVE_MQ_HOST
const port = process.env.ACTIVE_MQ_PORT

const destination = process.argv[1]
const event = process.argv[2]

const client = new Memo({
  host,
  port,
  destination
})

client.on('listening', () => console.log('Client is connected'))

await client.listen(event, async (data, e) => {

  const { eventId } = e

  console.log(`Event id: ${eventId}`)
  console.log(`Event data: ${data}`)

  return data

})

await client.block()

$ node listen.js "topic" "event"

Event id: 9f98d24c-9102-4111-82f8-ddb42846a311
Event data: eventdata

$ cat send.js

const Memo = require('memo')

const host = process.env.ACTIVE_MQ_HOST
const port = process.env.ACTIVE_MQ_PORT

const destination = process.argv[1]
const event = process.argv[2]
const data = process.argv[3]

const client = new Memo({
  host,
  port,
  destination
})

const res = await client.send(event, data)

console.log(res)

$ node send.js "topic" "event" "eventdata"

Versioning

We follow the Semantic Versioning Specification for our releases.

For a given version of memo, we will only increment the:

• MAJOR version when making an incompatible API change,
• MINOR version when adding functionality in a backwards compatible manner
• PATCH version when making backwards compatible changes/improvements/bug fixes.

If you are concerned about breaking changes, see the section above regarding version pinning.

Currently memo should be considered beta software.
