Before pushing code or sending a pull request, do the following:

• At the command line, run npm run lint at the top-level directory. This invokes lerna to check for lint errors in all of our packages.
• You can use eslint to fix some of the lint errors. To use it, go to the package that has errors and run lint-fix
• If there are any remaining lint errors, resolve them manually. Linting your code is a best practice that ensures good code quality so it's important that you don't skip this step.
