# Usage
You can use the `PdfService`, there is currently two methods
| | Description | Parameters |
|------------|----------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------|
| `generatePdfFromHtml` | | - `html`: The html to use to generate the pdf|
| `generatePdfFromTemplateString` | | - `template`: The template string to give to the handlebars service.
- `parameters`: The parameters to use inside the template|
| `generatePdfFromTemplateFile` | |- `file`:The template file to give to the handlebars service.
- `parameters`: The parameters to use inside the template|
Here is an example
```ts
@Controller()
export class AppController {
constructor(private readonly pdfService: PdfService) {}
@Get()
@Header('Cache-Control', 'none')
@Header('Content-Type', 'application/pdf')
async getPdf() {
const product = new Product();
product.amount = 53;
const pdf = await this.pdfService.generatePdfFromTemplateString(
'
Title
Product price: {{product.amount}}€',
{ product },
);
return pdf;
}
}
```
# Command
You can use the command `nestjs-pdf install` to install the browser you want to use.
You can specify 3 parameters:
- `--browser`: The browser to use for the PDF generation. Allowed values `chromium`, `chrome`, `chrome-headless-shell`, `firefox`, `chromedriver`([Official documentation of Browser](https://pptr.dev/browsers-api/browsers.browser))
- `--browser-tag`: The version of the browser to use for the PDF generation. Allowed values `stable`, `latest`, `beta`, `dev`, `canary`
- `--lock`: Define if you want to lock version of the browser. Allowed values `true`,`false`
# BaseUrl
Sometime you need to define the base url for the installation of the browser. You can use the `browserInstallBaseUrl` parameter to define it.
For example if you want to use `CHROMEHEADLESSSHELL` with `STABLE`, you may encounter an error like this:
```
Error: Download failed: server returned code 404. URL: https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/121.0.6167.184/mac-x64/chrome-headless-shell-mac-x64.zip
```
You can find the urls [here](https://googlechromelabs.github.io/chrome-for-testing/), and as you can the url are starting by `https://storage.googleapis.com/chrome-for-testing-public`.
So you can fix the error by adding the `browserInstallBaseUrl` parameter like this:
```ts
PdfModule.forRoot({
browserInstallBaseUrl:
'https://storage.googleapis.com/chrome-for-testing-public',
}),
```
# Known issues
- Currently, the pdf only works with fastify adapter
