# Follow these steps to convert HTML to PDF
- Step 1 - install the pdf generator package using the following command
`$ npm i pdf-generator-node --save`
> --save flag adds package name to package.json file.
- Step 2 - Add required packages and read HTML template
```javascript
//Required package
var pdf = require("pdf-generator-node");
var fs = require("fs");
// Read HTML Template
var html = fs.readFileSync("template.html", "utf8");
```
- Step 3 - Create your HTML Template
```html
Hello world!
User List
{{#each users}}
- Name: {{this.name}}
- Age: {{this.age}}
{{/each}}
```
- Step 4 - Provide pdf options
```javascript
var options = {
format: "A3",
landscape: false,
margin: {
top:"10mm",
bottom:"10mm",
left:"10mm",
right:"10mm"
},
headerTemplate: {
height: "45mm",
contents: 'Author: Shyam Hajare
'
},
footerTemplate: {
height: "28mm",
contents: {
first: 'Cover page',
2: 'Second page', // Any page number is working. 1-based index
default: '{{page}}/{{pages}}', // fallback value
last: 'Last Page'
}
}
};
```
- Step 5 - Provide HTML, user data and PDF path for output
```javascript
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: "buffer", // buffer || stream
};
```
- Step 6 - After setting all parameters, just pass document and options to `pdf.create` method.
```javascript
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
```js
{{#ifCond inputData "===" toCheckValue}}
```
```html
Hello world!
User List
{{#each users}}
- Name: {{this.name}}
- Age: {{#ifCond this.age '===' '26'}}
{{/ifCond}}
{{/each}}
```
Can check variables with different type ie _string_, _integer_, _boolean_, _double_
Other logical operators are-:
- ==
```js
{{#ifCond inputData "==" toCheckValue}}
```
- ===
```js
{{#ifCond inputData "===" toCheckValue}}
```
- !=
```js
{{#ifCond inputData "!=" toCheckValue}}
```
- !==
```js
{{#ifCond inputData "!==" toCheckValue}}
```
- <
```js
{{#ifCond inputData "<" toCheckValue}}
```
- <=
```js
{{#ifCond inputData "<=" toCheckValue}}
```
- '>
```js
{{#ifCond inputData ">" toCheckValue}}
```
- '>=
```js
{{#ifCond inputData ">=" toCheckValue}}
```
- &&
```js
{{#ifCond inputData "&&" toCheckValue}}
```
- ||
```js
{{#ifCond inputData "||" toCheckValue}}
```
##NOTE!!
You can only match 2 variables
