Boleto generator in Node.js

node-boleto

Standard - JavaScript Style Guide Quality Gate Status Coverage Maintainability Rating Reliability Rating Security Rating

Geração de boleto bancário em Node.js. Os algoritmos de geração da linha digitável e do código de barras foram inspirados no boletophp.

Bancos suportados

Instalação

npm install node-boleto

Exemplo de uso

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);

Adicionando novos bancos

Renderização do código de barras

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';
