# node-repl
an interactive repl for debugging node programs.
run a node program but also attach a repl to the same context that your code runs in so you can inspect + mess with stuff as your program is running
available as a command-line tool
[](https://nodei.co/npm/node-repl/)
currently this only works on node >=0.12 and iojs as it uses a generator to make the eval loop preserve scope.
## installation
```js
npm install node-repl -g
```
## CLI usage
```bash
$ node-repl
Usage: node-repl
$ node-repl your-program.js
>
```
## example
suppose we have a program called `hello.js` that has these contents:
```js
var pizza = 1
```
if you run `node-repl hello.js` you will get a repl, just like when you run `node`.
The difference is that this repl is running *in the same context as your program*.
```
$ node-repl hello.js
> 1 + 1 // we are in a node repl
2
> pizza // we can access variables in our program
1
>
```
