Use Case

As a driver engineer
I want to add BigInt EJSON parsing to js-bson
So that users can make use of native JS BigInts

Unknowns

Acceptance Criteria

Implementation Requirements

• Ensure that EJSON.parse can handle parsing of $numberLong based on the value of the useBigInt64 flag. If true then it should be converted to a BigInt, otherwise it will retain the current behaviour

Testing Requirements

• Unit tests that directly inspect output of parse when passed $numberLong
• Ensure that useBigInt64 defaults to false
• Ensure that when useBigInt64 is false, previously implemented behaviour is unchanged
• Ensure that examples in User-Facing syntax section of the design document are converted into unit tests

Documentation Requirements

• Update js-bson README to explain usage of useBigInt64 flag
