# stacktracify

Have you ever been faced with a stacktrace that looks like this?

```

TypeError h is not a function. (In 'h()', 'h' is undefined) 

    main.jsbundle:954:5353 

    main.jsbundle:112:423 p

    main.jsbundle:112:1740 

    main.jsbundle:112:423 p

    main.jsbundle:112:898 n

    main.jsbundle:112:1273 

    main.jsbundle:50:205 c

    main.jsbundle:50:1623 b

    main.jsbundle:50:488 _

    [native code] value

    [native code] value

```

...perhaps from production from a minified web JS bundle or a React Native error report.

**stacktracify takes a source map and a stack trace from your clipboard (or from a file) and outputs a readable stacktrace with proper line numbers for each line**

Example output:

```

TypeError h is not a function. (In 'h()', 'h' is undefined) 

    at getAuthToken (logic/api.js:67:20)

    at authRequest (logic/api.js:127:8)

    at data (logic/SaveQueue.js:30:20)

    at op (logic/SaveQueue.js:43:29)

    at __callImmediates (node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:143:11)

```

## Install

```

npm install -g stacktracify

```

## Usage

**Copy a minified stacktrace to your clipboard** - then run:

```

stacktracify /path/to/js.map

```

Can also read stacktrace from file. For more info:

```

stacktracify --help

```
