Changes

Summary of changes:

  • Refactor existing prototypes to ES6 classes. This includes getting rid of the wrapPropertyMethod which hides methods on these classes. Now it's possible for IDES to autodetect these methods.
  • Added eslint to catch mistakes during refactoring and to maintain es6 syntaxes in the future.
  • Improved formatting of JSDoc comments and removed some unnecessary tags like @class, @function and @memberof now when the classes are real classes and have real methods. All class methods which are forwarding all of their arguments (...args) still has their respective JSDoc @param tags which technically is wrong but since the underlying library works the way it does then it will have to be like that for now.
  • Removed moment devDep
  • Updated some testing dependencies like mocha and sinon.
  • Added node 16 to the ci test/build matrix.
  • Got rid of dependency on es6-promisify by using native Promise objects, much like es6-promisify did.
  • Got rid of the >10s long test should expire access token from cache by the expires_in setting by using sinons fake timers to advance time.

Testing

Test logic has not been altered other than conforming to the linting rules and es6 class syntax.

It tooks me some time to figure out why the tests were not working initially so if any newcomers see this you will need to install OpenSSL 1 (NOT 3 because that is not yet supported by the pem package) and make sure you remove the CRLF EOL in users.json test data file.

👋 Hi @hornta - you've clearly done a lot of work here, so many thanks

My concern is whether we need a breaking change for dropping support for older, albeit EOL, versions of Node. If that's the case we may be reluctant to take this PR if we don't want to do a major release. But I'll check with the team and get back to you.

Yea I agree that it should maybe be a breaking change since there is not really a good way of determining the minimum supported node version at this moment. However there are a bunch of object spread syntaxes in the code base right now which came to be supported after classes were supported in node so introducing classes should not cause a major version bump but I think it's quite good to define the supported engines.

@adamjmcgrath The CI tests doesn't want to start for some reason? Can I trigger then manually?

@hornta , our CI doesnt run on forks so no worries about it.

@hornta - thanks for raising this. Happy to review once you resolve the conflicts.

I've set up the CI to run on Node versions 8, 10, 12, 14 - as long as it passes on those (which es2017 should do) it should be fine.

I think it's quite good to define the supported engines.

I agree, but I don't want to introduce a breaking change, so could you remove the engine requirements

Thanks. I removed the engine requirements and resolved the merge conflicts. On an unrelated note, do you mind if node 16 is added as well since it's what I've been developing on and it seems to work great or what have your team decided?

Thanks, I'll take a look over this over the next day or so

Sure, feel free to add it to the matrix https://github.com/auth0/node-auth0/blob/master/.circleci/config.yml#L44

@hornta - you have some lint failures on CI https://app.circleci.com/pipelines/github/auth0/node-auth0/845/workflows/149addf8-9501-4952-af9e-c58c621a0a53/jobs/1213

I resolved the lint failres by setting the engines field in package.json to 8.3.0 since that's where node came to support object spread syntax.

However I noticed that ESLint failed as well for node 8 and 10 since ESLint only support node 12 and onward so I had to create a parallell job just for node 8 and 10 which just doesn't run the ESLint step. I don't know if it can be made prettier in the config.yml but I have limited experience with CircleCI config. It's kinda ugly to have to repeat the complete job but just removing the ESLint step.

I also noticed that the tests were failing for both node 8 and 10 because I updated mocha from major 6 to 9 and between these versions mocha dropped support for both 8 and 10 so I had to revert back the mocha upgrade to what we had before which is (6.1.0).
However by downgrading mocha, most of my tests failed because of a bug in mocha where it didn't handle rejected promises correctly when using async/await and that bug was fixed in mocha@8 so I tried to downgrade to mocha@8. However between [email protected] and mocha@8 it's dependency on yargs-parser dropped support for node 8 which is now causing our node 8 test runs to fail.

I don't feel like reverting all of the failing tests because of the bug which was fixed in a future mocha version so I guess this PR must then be on hold until node-auth0 decides to make a new major and drop support for 8 and hopefully 10 as well since most of our deps doesn't seem to support these.

Great. I aim to not let this rot away so I will keep this branch up to date because when this is in then it will be easier converting to typescript because it uses classes then.

@hornta

npx mocha@6 --reporter spec ./test/**/*.tests.js is passing for me on Node 8. Could you conditionally target that instead of npm test for the Node 8 job?

Thanks, it seems to not throw errors now which is nice.

What's the issue with using proxyquire?

I think I didn't see a need for it , also it doesn't work when using ESM(which this library doesn't yet but hopefully will sometime :-)). I would want to remove that dependency completely because I think if it's needed then simple dependency injection can be used as I've done here.

I'd rather avoid adding new options to this class just for testing.

If it comes to that we can always switch to something like jest, which has good options for stubbing esm

You can use built in promisify - you don't need es6-promisify

Alright so I reverted the changes so that proxyquire are used now. I now know why I wanted to remove proxyquire and it was because proxyquire throw an error when I tried to stub a sinon.spy()(because it's missing a .prototype property) and I don't know why it's like that, it must have been because of some updated dependency. Whatever I fixed it by attaching an empty prototype object myStub.prototype = {}. Not the prettiest but it doesn't throw now.

FYI the coverage changes are as a result of changing a bunch of wrapPropertyMethod's to functions with body's
