Basic motivation

• We want to observe our systems. Sometimes we may want a log with messages in it, other times just a metric is fine. BUT the times we want either of these can be arbitrary... don't want to have to make a release of an app just because we're in the middle of an incident and want more detailed logs of something.
• Want to untangle next-metrics from express
• BUT ideally want any new thing to be reasonably backwards compatible

Sketch proposal

ft-observable

• collects both logs & metrics in a unified interface

You might not need lodash

_.chunk

(arr, size) => [...Array(Math.ceil(arr.length/size))].map(() => arr.splice(0, size))

_.compact

(arr) => arr.filter(it => !!it)

_.concat

(arr, values) => arr.concat(...values)

Transform handlers compatible with express, lambda etc to each other

e.g. 


reckie.lambdaToExpress = handler => {
  return (req, res) => {
    const event = eventFromRequest(req);
    const callback = callbackFromResponse(res);
    handler(event, null, callback);

// 1. want an object of promises kicked off by each task
// 2. each task declares its dependencies
// 3. if no dependencies it runs immediately
// 4. if dependencies, waits for them
// 5. unified pattern

const tasks = {};
// str, arr, (req, headers, deps) => headers
const taskRunner = {

Remember to also search the codebase for uri encoded versions of the urls as these will need updating too.

We don't have a switch off date for next-geebee yet, but as it's a next project experiment, rather than a platform,
