## Installation
```bash
npm i vue-papa-parse
# or
yarn add vue-papa-parse
```
## Default import
```javascript
import Vue from 'vue'
import VuePapaParse from 'vue-papa-parse'
Vue.use(VuePapaParse)
```
## Usage
### PARSE STRING
```javascript
this.$papa.parse(csvString[, config])
```
read the docs for [parsing csv strings](https://www.papaparse.com/docs#strings)
### PARSE LOCAL FILES
```javascript
this.$papa.parse(file, config)
```
read the docs for [parsing local files](https://www.papaparse.com/docs#local-files)
### PARSE REMOTE FILE
```javascript
this.$papa.parse(url, {
download: true,
// rest of config ...
})
```
read the docs for [parsing remote files](https://www.papaparse.com/docs#remote-files)
>**PARSE Converts CSV to JSON**
>**The Parse Result Object**
>A parse result always contains three objects: data, errors, and meta. Data and errors are arrays, and meta is an object. In the step callback, the data array will only contain one element. [See the parse results object docs.](https://www.papaparse.com/docs#results)
>**The Parse Config Object**
>The `parse` function may be passed a configuration object. It defines settings, behavior, and callbacks used during parsing. Any properties left unspecified will resort to their default values. [See all config options for parse.](https://www.papaparse.com/docs#config)
### UNPARSE
```javascript
this.$papa.unparse(data[, config])
```
read the docs for [unparsing data](https://www.papaparse.com/docs#unparse)
>**UNPARSE Converts JSON to CSV**
> Papa's `unparse` utility writes out correct delimited text strings given an array of arrays or an array of objects. [See all config options for unparse.](https://www.papaparse.com/docs#unparse-config-default)
### DOWNLOAD
*Extended Papa to include a simple download method. This allows you to easily download a ```.csv``` file for JSON that has been converted to CSV.*
> This method takes two arguments:
>
> - ```csv``` usually the the results from ```this.$papa.unparse(data[, config])```)
> - ```title``` The title of the downloaded .csv.
note: no need to add the .csv extension.
```javascript
this.$papa.download(csv, title)
```
### DEDUPE
*Extended Papa to include a simple deduplication method. This allows you to simply remove exact duplicate entries from a parsed CSV file.*
> This method takes one argument:
>
> - ```data``` usually the data key from the result object returned from ```this.$papa.parse(mixed[, config])```)
