# Examples of use of [pdfreader](https://github.com/adrienjoly/npm-pdfreader)
## How to install and run
```sh
git clone https://github.com/adrienjoly/npm-pdfreader-example.git
cd npm-pdfreader-example
npm install
node parseItems.js
```
## 1. Parsing lines of text
Here is the code required to convert this PDF file into text:
```js
var pdfreader = require('pdfreader');
var rows = {}; // indexed by y-position
function printRows() {
Object.keys(rows) // => array of y-positions (type: float)
.sort((y1, y2) => parseFloat(y1) - parseFloat(y2)) // sort float positions
.forEach((y) => console.log((rows[y] || []).join('')));
}
new pdfreader.PdfReader().parseFileItems('CV_ErhanYasar.pdf', function(err, item){
if (!item || item.page) {
// end of file, or page
printRows();
console.log('PAGE:', item.page);
rows = {}; // clear rows for next page
}
else if (item.text) {
// accumulate text items into rows object, per line
(rows[item.y] = rows[item.y] || []).push(item.text);
}
});
```
## 2. Parsing a table
Here is the code required to convert this PDF file into a textual table:
```js
var pdfreader = require('pdfreader');
const nbCols = 2;
const cellPadding = 40; // each cell is padded to fit 40 characters
const columnQuantitizer = (item) => parseFloat(item.x) >= 20;
const padColumns = (array, nb) =>
Array.apply(null, {length: nb}).map((val, i) => array[i] || []);
// .. because map() skips undefined elements
const mergeCells = (cells) => (cells || [])
.map((cell) => cell.text).join('') // merge cells
.substr(0, cellPadding).padEnd(cellPadding, ' '); // padding
const renderMatrix = (matrix) => (matrix || [])
.map((row, y) => padColumns(row, nbCols)
.map(mergeCells)
.join(' | ')
).join('\n');
var table = new pdfreader.TableParser();
new pdfreader.PdfReader().parseFileItems(filename, function(err, item){
if (!item || item.page) {
// end of file, or page
console.log(renderMatrix(table.getMatrix()));
console.log('PAGE:', item.page);
table = new pdfreader.TableParser(); // new/clear table for next page
} else if (item.text) {
// accumulate text items into rows object, per line
table.processItem(item, columnQuantitizer(item));
}
});
```
