|
|
||
|
|
[`json-parse-even-better-errors`](https://github.com/npm/json-parse-even-better-errors) is a Node.js library for
|
||
|
|
getting nicer errors out of `JSON.parse()`, including context and position of the parse errors.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
`$ npm install --save json-parse-even-better-errors`
|
||
|
|
|
||
|

### Example
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
const parseJson = require('json-parse-even-better-errors')
|
||
|
|
|
||
|
|
parseJson('"foo"')
|
||
|
|
parseJson('garbage') // more useful error message
|
||
|
|
```
|
||
|
|
|
||
|
|
### Features
|
||
|
|
|
||
|
|
* Like JSON.parse, but the errors are better.
|
||
|
|
|
||
|
|
### API
|
||
|
|
|
||
|
|
#### <a name="parse"></a> `parse(txt, reviver = null, context = 20)`
|
||
|
|
|
||
|
|
Works just like `JSON.parse`, but will include a bit more information when an
|
||
|
|
error happens. This throws a `JSONParseError`.
|
||
|
|
|
||
|
|
#### <a name="jsonparseerror"></a> `class JSONParseError(er, text, context = 20, caller = null)`
|
||
|
|
|
||
|
|
Extends the JavaScript `SyntaxError` class to parse the message and provide
|
||
|
|
better metadata.
|
||
|
|
|
||
|
|
Pass in the error thrown by the built-in `JSON.parse`, and the text being
|
||
|
|
parsed, and it'll parse out the bits needed to be helpful.
|
||
|
|
|
||
|
|
`context` defaults to 20.
|
||
|
|
|
||
|
|
Set a `caller` function to trim internal implementation details out of the
|
||
|
|
stack trace. When calling `parseJson`, this is set to the `parseJson`
|
||
|
|
function. If not set, then the constructor defaults to itself, so the
|
||
|
|
stack trace will point to the spot where you call `new JSONParseError`.
