Follow these steps to convert HTML to PDF

  • Step 1 - install the pdf creator package using the following command

    $ npm i pdf-creator-node --save

    --save flag adds package name to package.json file.

  • Step 2 - Add required packages and read HTML template

    //Required package
    var pdf = require("pdf-creator-node");
    var fs = require("fs");
    
    // Read HTML Template
    var html = fs.readFileSync("template.html", "utf8");
  • Step 3 - Create your HTML Template

    <!DOCTYPE html>
    <html>
      <head>
        <meta charset="utf-8" />
        <title>Hello world!</title>
      </head>
      <body>
        <h1>User List</h1>
        <ul>
          {{#each users}}
          <li>Name: {{this.name}}</li>
          <li>Age: {{this.age}}</li>
          <br />
          {{/each}}
        </ul>
      </body>
    </html>
  • Step 4 - Provide format and orientation as per your need

    "height": "10.5in", // allowed units: mm, cm, in, px

    "width": "8in", // allowed units: mm, cm, in, px

    • or -

    "format": "Letter", // allowed units: A3, A4, A5, Legal, Letter, Tabloid

    "orientation": "portrait", // portrait or landscape

        var options = {
            format: "A3",
            orientation: "portrait",
            border: "10mm",
            header: {
                height: "45mm",
                contents: '<div style="text-align: center;">Author: Shyam Hajare</div>'
            },
            footer: {
                height: "28mm",
                contents: {
                    first: 'Cover page',
                    2: 'Second page', // Any page number is working. 1-based index
                    default: '<span style="color: #444;">{{page}}</span>/<span>{{pages}}</span>', // fallback value
                    last: 'Last Page'
                }
            }
        };
  • Step 5 - Provide HTML, user data and PDF path for output

    var users = [
      {
        name: "Shyam",
        age: "26",
      },
      {
        name: "Navjot",
        age: "26",
      },
      {
        name: "Vitthal",
        age: "26",
      },
    ];
    var document = {
      html: html,
      data: {
        users: users,
      },
      path: "./output.pdf",
      type: "",
    };
    // By default a file is created but you could switch between Buffer and Streams by using "buffer" or "stream" respectively.
  • Step 6 - After setting all parameters, just pass document and options to pdf.create method.

    pdf
      .create(document, options)
      .then((res) => {
        console.log(res);
      })
      .catch((error) => {
        console.error(error);
      });

If Conditional Checks

You can do conditional checks by calling helper block ifCond example

{{#ifCond inputData "===" toCheckValue}}
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8" />
    <title>Hello world!</title>
  </head>
  <body>
    <h1>User List</h1>
    <ul>
      {{#each users}}
      <li>Name: {{this.name}}</li>
      <li>Age: {{#ifCond this.age '===' '26'}}</li>
      <br />
      {{/ifCond}}
      {{/each}}
    </ul>
  </body>
</html>

Can check variables with different type ie string, integer, boolean, double

Other logical operators are-:

  • ==
     {{#ifCond inputData "==" toCheckValue}}
  • ===
     {{#ifCond inputData "===" toCheckValue}}
  • !=
     {{#ifCond inputData "!=" toCheckValue}}
  • !==
     {{#ifCond inputData "!==" toCheckValue}}
  • <
     {{#ifCond inputData "<" toCheckValue}}
  • <=
     {{#ifCond inputData "<=" toCheckValue}}
  • '>
     {{#ifCond inputData ">" toCheckValue}}
  • '>=
     {{#ifCond inputData ">=" toCheckValue}}
  • &&
     {{#ifCond inputData "&&" toCheckValue}}
  • ||
     {{#ifCond inputData "||" toCheckValue}}

##NOTE!! You can only match 2 variables
