NODE 12

dd-trace-js

Hi I'm Aleffeh, I did this fork in order to support node12 as min version to datadog-ci due to my current project requirements.

THIS FORK IS NOT GUARANTED TO WORK, DATADOG USES NODE14 AS MIN VERSION.

Security Vulnerabilities

Requirements

Since this project supports multiple Node versions, using a version manager such as nvm is recommended.

We use yarn for its workspace functionality, so make sure to install that as well.

To get started once you have Node and yarn installed, run:

$ yarn

Testing

Before running the tests, the data stores need to be running. The easiest way to start all of them is to use the provided docker-compose configuration:

$ docker-compose up -d -V --remove-orphans --force-recreate

Unit Tests

To run the unit tests, use:

$ yarn test

To run the unit tests continuously in watch mode while developing, use:

$ yarn tdd

Memory Leaks

To run the memory leak tests, use:

$ yarn leak

Please note that memory leak tests only run on Node >=8.

Linting

We use ESLint to make sure that new code is conform to our coding standards.

To run the linter, use:

$ yarn lint

Continuous Integration

We rely on CircleCI 2.0 for our tests. If you want to test how the CI behaves locally, you can use the CircleCI Command Line Interface as described here: https://circleci.com/docs/2.0/local-jobs/

After installing the circleci CLI, simply run one of the following:

$ circleci build --job lint
$ circleci build --job node-leaks
$ circleci build --job node-core-8
$ circleci build --job node-core-10
$ circleci build --job node-core-12
$ circleci build --job node-core-latest

Benchmarks

When two or more approaches must be compared, please write a benchmark in the benchmark/index.js module so that we can keep track of the most efficient algorithm. To run your benchmark, just:

$ yarn bench
