    NPM version NPM Licence Snyk Vulnerabilities js-standard-style NPM downloads

    Nodejs client SDK for Pdfbix

    Pdfbix is one of the cheapest tool to convert your HTML or URL to pdf. You can generate pdf at the cost of setting up your own server. It's a tool developed by developers for developer so that they can focus on business logic & forget about all the hassle of maintaing & scaling servers for generating pdf.


    Download the NPM module

    npm install pdfbix --save


    Create an account at Pdfbix to get your API key.


    Initialize the Client

    Require the package in your code & create a pdfbix object.

    const { Pdfbix } = require('pdfbix');
    const pdfbix = new Pdfbix({ authKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' });

    All options that can be passed while creating object

    Key Value Required/Optional Default Description
    authKey String required Required to validate request made via sdk
    baseUrl String optional Used as base URL for all calls
    apiVersion String optional v1 Changed when breaking changes are added

    Convert URL to PDF

    // All options mentioned later in doc
    const args = { fileName: 'example.pdf' }
    pdfbix.convertUrlToPdf('', args).then(res => {
    }).catch(error => {

    Convert HTML to PDF

    // All options mentioned later in doc
    const args = { fileName: 'example.pdf' }
    pdfbix.convertHtmlToPdf('', args).then(res => {
    }).catch(error => {

    Async-Await Implementation

    Above result can also be achieved by using async & await

    try {
        const result = await pdfbix.convertUrlToPdf('', args)
    } catch (error) {

    All options that can be passed in args

    Key Value Required/Optional Default Description
    toUrl Boolean optional true true: return a link to download pdf; false: return base64 representation of pdf
    fileName String optional {requestId}_{currentDatetime} Custom file name given to file
    enableCustomStorage Boolean optional false If enabled all files will be saved to configured s3 bucket in dashboard
    customStorage String optional Will only work if enableCustomStorage is enabled. Valid options are aws and gcp
    pdfOpts Object optional {} Puppeteer options that can be passed, to configure final pdf

    All options that can be passed into pdfOpts can be found here


    It's recommended to enclose pdfbix call into try-catch block to handle unexpected response. Here are possible result format you can expect.

    Success Response

      "statusCode": 200,
      "data": {
        "content": "",
        "isBase64Encoded": false,
        "fileSize": 35.14258,
        "timeTaken": 6.409,
        "cost": 0.00446

    If isBase64Encoded is true then content will contain base64 string representing final pdf, you might need to parse that base64 String. isBase64Encoded will be true when you set toUrl as false in args while calling convertHtmlToPdf or convertUrlToPdf.

    Error Response

      "statusCode": 401,
      "error": {
        "name": "BackendClientError",
        "code": "ERR_INVALID_TOKEN",
        "message": "Token you're passing is invalid.",
        "statusCode": 401,
        "errorData": {}
      "message": "Token you're passing is invalid."

    Enable google cloud Storage

    You need to create bucket in GCP using console or cli. To do so, you can follow the steps mentioned here.

    To enable upload using code you need to genreate credentials or a role with storage.objects.create permission. You can follow the steps in this guide to upload objects into bucket.
