|
> Captures and cleans stack traces.

|
|
|
|
|
|
Extracted from `lib/stack.js` in the [`node-tap` project](https://github.com/tapjs/node-tap)
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install --save stack-utils
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const StackUtils = require('stack-utils');
|
|
const stack = new StackUtils({cwd: process.cwd(), internals: StackUtils.nodeInternals()});
|
|
|
|
console.log(stack.clean(new Error().stack));
|
|
// outputs a beautified stack trace
|
|
```
|
|
|
|
|
|
## API
|
|
|
|
|
|
### new StackUtils([options])
|
|
|
|
Creates a new `stackUtils` instance.
|
|
|
|
#### options
|
|
|
|
##### internals
|
|
|
|
Type: `array` of `RegularExpression`s
|
|
|
|
A set of regular expressions that match internal stack stack trace lines which should be culled from the stack trace.
|
|
The default is `StackUtils.nodeInternals()`, this can be disabled by setting `[]` or appended using
|
|
`StackUtils.nodeInternals().concat(additionalRegExp)`. See also `ignoredPackages`.
|
|
|
|
##### ignoredPackages
|
|
|
|
Type: `array` of `string`s
|
|
|
|
An array of npm modules to be culled from the stack trace. This list will mapped to regular
|
|
expressions and merged with the `internals`.
|
|
|
|
Default `''`.
|
|
|
|
##### cwd
|
|
|
|
Type: `string`
|
|
|
|
The path to the current working directory. File names in the stack trace will be shown relative to this directory.
|
|
|
|
##### wrapCallSite
|
|
|
|
Type: `function(CallSite)`
|
|
|
|
A mapping function for manipulating CallSites before processing. The first argument is a CallSite instance, and the function should return a modified CallSite. This is useful for providing source map support.
|
|
|
|
|
|
### StackUtils.nodeInternals()
|
|
|
|
Returns an array of regular expressions that be used to cull lines from the stack trace that reference common Node.js internal files.
|
|
|
|
|
|
### stackUtils.clean(stack, indent = 0)
|
|
|
|
Cleans up a stack trace by deleting any lines that match the `internals` passed to the constructor, and shortening file names relative to `cwd`.
|
|
|
|
Returns a `string` with the cleaned up stack (always terminated with a `\n` newline character).
|
|
Spaces at the start of each line are trimmed, indentation can be added by setting `indent` to the desired number of spaces.
|
|
|
|
#### stack
|
|
|
|
*Required*
|
|
Type: `string` or an `array` of `string`s
|
|
|
|
|
|
### stackUtils.capture([limit], [startStackFunction])
|
|
|
|
Captures the current stack trace, returning an array of `CallSite`s. There are good overviews of the available CallSite methods [here](https://github.com/v8/v8/wiki/Stack%20Trace%20API#customizing-stack-traces), and [here](https://github.com/sindresorhus/callsites#api).
|
|
|
|
#### limit
|
|
|
|
Type: `number`
|
|
Default: `Infinity`
|
|
|
|
Limits the number of lines returned by dropping all lines in excess of the limit. This removes lines from the stack trace.
|
|
|
|
#### startStackFunction
|
|
|
|
Type: `function`
|
|
|
|
The function where the stack trace should start. The first line of the stack trace will be the function that called `startStackFunction`. This removes lines from the end of the stack trace.
|
|
|
|
|
|
### stackUtils.captureString([limit], [startStackFunction])
|
|
|
|
Captures the current stack trace, cleans it using `stackUtils.clean(stack)`, and returns a string with the cleaned stack trace. It takes the same arguments as `stackUtils.capture`.
|
|
|
|
|
|
### stackUtils.at([startStackFunction])
|
|
|
|
Captures the first line of the stack trace (or the first line after `startStackFunction` if supplied), and returns a `CallSite` like object that is serialization friendly (properties are actual values instead of getter functions).
|
|
|
|
The available properties are:
|
|
|
|
- `line`: `number`
|
|
- `column`: `number`
|
|
- `file`: `string`
|
|
- `constructor`: `boolean`
|
|
- `evalOrigin`: `string`
|
|
- `native`: `boolean`
|
|
- `type`: `string`
|
|
- `function`: `string`
|
|
- `method`: `string`
|
|
|
|
### stackUtils.parseLine(line)
|
|
|
|
Parses a `string` (which should be a single line from a stack trace), and generates an object with the following properties:
|
|
|
|
- `line`: `number`
|
|
- `column`: `number`
|
|
- `file`: `string`
|
|
- `constructor`: `boolean`
|
|
- `evalOrigin`: `string`
|
|
- `evalLine`: `number`
|
|
- `evalColumn`: `number`
|
|
- `evalFile`: `string`
|
|
- `native`: `boolean`
|
|
- `function`: `string`
|
|
- `method`: `string`
