Our various configurations for nyc based code coverage. Geared for our specific needs, but feel free to use it if helps you!

Install the nyc-config module as a dev dependency:

npm i @swellaby/nyc-config --save-dev

Add an extends key to your nyc config file and specify the value of the configuration you want to use:

For example, to use our default nyc configuration add the following to your .nycrc file:

{
    ...
    "extends": "@swellaby/nyc-config",
    ...
}

Our base configuration defines a few core configuration settings:

• reporters - html, lcov, cobertura, text, and text-summary
• cache - true
• all - true
• per-file - true
• report-dir - .coverage/

You can utilize our base configuration by adding an extends key to your nyc config file and specifying the value of @swellaby/nyc-config/base. For example:

{
    ...
    "extends": "@swellaby/nyc-config/base",
    ...
}

Our complete coverage configuration enforces 100% code coverage. It is the default configuration specified by this config module. It extends our base configuration with the following settings:

• check-coverage - true
• lines - 100
• statements - 100
• functions - 100
• branches - 100

This config will be used by adding the config value to the extends key in your nyc config file.

{
    ...
    "extends": "@swellaby/nyc-config",
    ...
}

We also have a configuration that enforces code coverage levels with lower threshold levels. It similarly extends our base configuration but uses defines the following coverage levels:

• check-coverage - true
• lines - 75
• statements - 75
• functions - 80
• branches - 70

You can utilize our partial coverage configuration by adding an extends key to your [nyc config file][nyc-config-url] and specifying the value of @swellaby/nyc-config/partial-coverage. For example:

{
    ...
    "extends": "@swellaby/nyc-config/partial-coverage",
    ...
}

All configurations are also accessible programmatically and can be accessed via the relevant property after importing the @swellaby/nyc-config module. For example:

const nycConfig = require('@swellaby/nyc-config');

const baseConfig = nycConfig.baseConfig;
const partialCoverageConfig = nycConfig.partialCoverageConfig;
