Geração de boleto bancário em Node.js. Os algoritmos de geração da linha digitável e do código de barras foram inspirados no boletophp.
npm install node-boleto
Emitindo um boleto:
var Boleto = require('node-boleto').Boleto;
var boleto = new Boleto({
'banco': "santander", // nome do banco dentro da pasta 'banks'
'data_emissao': new Date(),
'data_vencimento': new Date(new Date().getTime() + 5 * 24 * 3600 * 1000), // 5 dias futuramente
'valor': 1500, // R$ 15,00 (valor em centavos)
'nosso_numero': "1234567",
'numero_documento': "123123",
'cedente': "Pagar.me Pagamentos S/A",
'cedente_cnpj': "18727053000174", // sem pontos e traços
'agencia': "3978",
'codigo_cedente': "6404154", // PSK (código da carteira)
'carteira': "102"
});
console.log("Linha digitável: " + boleto['linha_digitavel'])
boleto.renderHTML(function(html){
console.log(html);
});
Parseando o arquivo-retorno EDI do banco:
var ediParser = require('node-boleto').EdiParser,
fs = require('fs');
var ediFileContent = fs.readFileSync("arquivo.txt").toString();
var parsedFile = ediParser.parse("santander", ediFileContent);
console.log("Boletos pagos: ");
console.log(parsedFile.boletos);
Atualmente, há duas maneiras de renderizar o código de barras: img e bmp.
A engine img utiliza imagens brancas e pretas intercaladas para gerar o código de barras. Dessa forma, todos os browsers desde o IE6 são suportados. Esse modo de renderização, porém, é um pouco mais pesado, já que muitas divs são inseridas no HTML para a renderização.
A engine bmp aproveita da característica monodimensional dos códigos de barra e gera apenas a primeira linha de pixels do boleto, repetindo as outras linhas por CSS. É mais leve e funciona na maioria dos browser - IE apenas a partir da versão 8.
Para alterar a engine de renderização padrão:
Boleto.barcodeRenderEngine = 'bmp';
