| ## istanbul-lib-coverage
 | |
| 
 | |
| [](https://greenkeeper.io/)
 | |
| [](https://travis-ci.org/istanbuljs/istanbul-lib-coverage)
 | |
| 
 | |
| An API that provides a read-only view of coverage information with the ability
 | |
| to merge and summarize coverage info.
 | |
| 
 | |
| Supersedes `object-utils` and `collector` from the v0 istanbul API.
 | |
| 
 | |
| See the docs for the full API.
 | |
| 
 | |
| ```js
 | |
| var libCoverage = require('istanbul-lib-coverage');
 | |
| var map = libCoverage.createCoverageMap(globalCoverageVar);
 | |
| var summary = libCoverage.createCoverageSummary();
 | |
| 
 | |
| // merge another coverage map into the one we created
 | |
| map.merge(otherCoverageMap);
 | |
| 
 | |
| // inspect and summarize all file coverage objects in the map
 | |
| map.files().forEach(function(f) {
 | |
|     var fc = map.fileCoverageFor(f),
 | |
|         s = fc.toSummary();
 | |
|     summary.merge(s);
 | |
| });
 | |
| 
 | |
| console.log('Global summary', summary);
 | |
| ```
