Node build without crypto or buffertools

[SimonWoolf]

https://app.intercom.io/a/apps/ua39m1ld/inbox/all/conversations/5952016749 has made me wonder if we should offer a node package without cryptojs and buffertools (like ably.noencryption.js for the browser), for usecases like using on AWS Lambda, where large package sizes (npm package is > 10MB at the moment, mostly cryptojs)) and having natively compiled modules are a pain.

You could take a similar approach to ably-ruby-rest where it simply references ably-js as a sub-module thus allowing it to skip all dependencies but use most of the code

@mattheworiordan possible be more explicit ?
I have a node app that runs in AWS, and what exactly should be go into package.json and the import line?

Here is the error from AWS lambda

{
  "errorMessage": "Cannot find module './build/Debug/buffertools.node'",
  "errorType": "Error",
  "stackTrace": [
    "Function.Module._load (module.js:276:25)",
    "Module.require (module.js:353:17)",
    "require (internal/module.js:12:17)",
    "Object.<anonymous> (/var/task/node_modules/buffertools/buffertools.js:26:20)",
    "Module._compile (module.js:409:26)",
    "Object.Module._extensions..js (module.js:416:10)",
    "Module.load (module.js:343:32)",
    "Function.Module._load (module.js:300:12)",
    "Module.require (module.js:353:17)",
    "require (internal/module.js:12:17)"
  ]

@leozc that note was for Simon to look at, probably not something we could easily explain how you can do it. Can you wait till early next week as we may be able to make a release that does not depend on buffertools?

[mattheworiordan]

@SimonWoolf we need to look at this on Monday as @paddybyers has confirmed Buffertools is not needed (Node.js 4.3.2 on Lambda has Buffer support, it was introduced in 0.11!).

Also, it seems crypto is part of Node.js core so shouldn't be an issue.

We need to remove BufferTools and check that it works in Lambda, then bump a release and add a note that we no longer support Node < 0.11

Fixed by #340, released as part of ably-js 0.8.38.
