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.createmethod.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
