Extract an array of pages/text from a pdf
npm install pdf2textExtract text from a pdf into an array of pages / text arrays. Useful for parsing on structured pdf text. Uses no external dependecies other than npm modules.
Modified from Brian C's pdf-text and using Mozilla's pdf.js via pdf2json.
``sh`
npm install pdf2text
`js
var pdf2Text = require('pdf2text')
var pathToPdf = __dirname + "/info.pdf"
pdf2Text(pathToPdf).then(function(pages) {
//pages is an array of string arrays
//loosely corresponding to text objects within the pdf
})
//or parse a buffer of pdf data
//this is handy when you already have the pdf in memory
//and don't want to write it to a temp file
var fs = require('fs')
var buffer = fs.readFileSync(pathToPdf)
pdf2Text(buffer).then(function(pages) {
})

#### pdf2text(string pathToPdfFile): Promise.
Promise returns an array Pages, which contains an array of all the strings on a page. The array is ordered similarly to how the text appears on the page, making it possible to extract key pieces by finding them based on how they relate to other 'known' pieces of text in the page.
#### pdfText(Buffer bufferOfPdfContents): Promise.
Optionally pass a buffer of pdf data instead of a path to the file.
