## istanbul-lib-instrument
[](https://travis-ci.org/istanbuljs/istanbul-lib-instrument)
Istanbul instrumenter library.
Version 1.1.x now implements instrumentation using `Babel`. The implementation is inspired
by prior art by @dtinth as demonstrated in the `__coverage__` babel plugin.
It provides 2 "modes" of instrumentation.
- The old API that is mostly unchanged (except for incompatibilities noted) and
performs the instrumentation using babel as a library.
- A `programVisitor` function for the Babel AST that can be used by a Babel plugin
to emit instrumentation for ES6 code directly without any source map
processing. This is the preferred path for babel users. The Babel plugin is
called `babel-plugin-istanbul`.
Incompatibilities and changes to instrumentation behavior can be found in
[v0-changes.md](v0-changes.md).
