Bump mongodb from 3.2.7 to 4.0.0

[dependabot-preview]

Bumps mongodb from 3.2.7 to 4.0.0.

Release notes

Sourced from mongodb's releases.

v4.0.0

The MongoDB Node.js team is delighted to announce the major version release 4.0.0 of the MongoDB Node.js Driver!

Release Highlights

We finally did it! The major version release of the MongoDB driver is now generally available! This release represents over a year's worth of effort that couldn't have been done without stellar contributions from the community and our Node.js DBX team. We hope you give it a try and are able to upgrade smoothly! 🎉

The biggest news is our migration to Typescript 🥳 offering first class support of type definitions in the driver itself.

Some cool new MongoDB 5.0 features now supported in the driver are:

• Native support for Time Series Collections
  • Time series collections efficiently store sequences of measurements over a period of time. Compared to normal collections, storing time series data in time series collections improves query efficiency and reduces the disk usage for time series data and secondary indexes
• Snapshot reads on secondaries
  • Support for read concern level "snapshot" (non-speculative) for read commands outside of transactions, including on secondaries. The snapshot reads on secondaries feature allows users to perform analytics with snapshot isolation on dedicated secondaries, including long running snapshot reads.

Below are only the changes since our last beta release, for the full set of breaking changes look at the upgrade guide here and for the full set of new features, take a look here.

Changes in 4.x (and how to migrate!)

Hello dear reader, thank you for adopting version 4.x of the MongoDB Node.js driver, from the bottom of our developer hearts we thank you so much for taking the time to upgrade to our latest and greatest offering of a stunning database experience. We hope you enjoy your upgrade experience and this guide gives you all the answers you are searching for. If anything, and we mean anything, hinders your upgrade experience please let us know via JIRA. We know breaking changes are hard but they are sometimes for the best. Anyway, enjoy the guide, see you at the end!

Key Changes

Typescript

We've migrated the driver to Typescript! Users can now harness the power of type hinting and intellisense in editors that support it to develop their MongoDB applications. Even pure JavaScript projects can benefit from the type definitions with the right linting setup. Along with the type hinting there's consistent and helpful docs formatting that editors should be able to display while developing. Recently we migrated our BSON library to TypeScript as well, this version of the driver pulls in that change.

Community Types users (@​types/mongodb)

If you are a user of the community types (@​types/mongodb) there will likely be compilation errors while adopting the types from our codebase. Unfortunately we could not achieve a one to one match in types due to the details of writing the codebase in Typescript vs definitions for the user layer API along with the breaking changes of this major version. Please let us know if there's anything that is a blocker to upgrading on JIRA.

Node.js Version

We now require node 12.9 or greater for version 4 of the driver. If that's outside your support matrix at this time, that's okay! Bug fix support for our 3.x branch will not be ending until summer 2022, which has support going back as far as Node.js v4!

Cursor changes

Affected classes:

• AbstractCursor
• FindCursor
• AggregationCursor
• ChangeStreamCursor
  • This is the underlying cursor for ChangeStream
• ListCollectionsCursor

Our Cursor implementation has been updated to clarify what is possible before and after execution of an operation. Take this example:

const cursor = collection.find({ a: 2.3 }).skip(1);
for await (const doc of cursor) {
  console.log(doc);
  fc.limit(1); // bad.
}

Change counts above are quantified counts, based on the PullRequestQuantifier customizations.

Why proper sizing of changes matters

Optimal pull request sizes drive a better predictable PR flow as they strike a
balance between between PR complexity and PR review overhead. PRs within the
optimal size (typical small, or medium sized PRs) mean:

• Fast and predictable releases to production:
  • Optimal size changes are more likely to be reviewed faster with fewer
    iterations.
  • Similarity in low PR complexity drives similar review times.
• Review quality is likely higher as complexity is lower:
  • Bugs are more likely to be detected.
  • Code inconsistencies are more likely to be detetcted.
• Knowledge sharing is improved within the participants:
  • Small portions can be assimilated better.
• Better engineering practices are exercised:
  • Solving big problems by dividing them in well contained, smaller problems.
  • Exercising separation of concerns within the code changes.

What can I do to optimize my changes

• Use the PullRequestQuantifier to quantify your PR accurately
  • Create a context profile for your repo using the context generator
  • Exclude files that are not necessary to be reviewed or do not increase the review complexity. Example: Autogenerated code, docs, project IDE setting files, binaries, etc. Check out the Excluded section from your prquantifier.yaml context profile.
  • Understand your typical change complexity, drive towards the desired complexity by adjusting the label mapping in your prquantifier.yaml context profile.
  • Only use the labels that matter to you, see context specification to customize your prquantifier.yaml context profile.
• Change your engineering behaviors
  • For PRs that fall outside of the desired spectrum, review the details and check if:
    • Your PR could be split in smaller, self-contained PRs instead
    • Your PR only solves one particular issue. (For example, don't refactor and code new features in the same PR).

How to interpret the change counts in git diff output

• One line was added: +1 -0
• One line was deleted: +0 -1
• One line was modified: +1 -1 (git diff doesn't know about modified, it will
  interpret that line like one addition plus one deletion)
• Change percentiles: Change characteristics (addition, deletion, modification)
  of this PR in relation to all other PRs within the repository.
