How to Use A Custom Font In Puppeteer Running on an Ubuntu Server?

To use a custom font in Puppeteer running on an Ubuntu server, you first need to upload the custom font files to the server. Then, you can use Puppeteer's page.setExtraHTTPHeaders method to load the font files when creating a new page.

You will need to specify the custom font in the CSS using @font-face rule and specify the path to the font file on the server. Make sure to update the font-family in your CSS to use the custom font.

Alternatively, you can also use Google Fonts or other hosted font services by linking to the font in your HTML or CSS files.

Overall, make sure your server has proper access permissions for the font files and ensure that the font is loaded correctly in your Puppeteer script.

What is the best practice for managing multiple custom fonts in Puppeteer?

The best practice for managing multiple custom fonts in Puppeteer is to preload the fonts before rendering the page. This can be done by using the FontFace API to define and load each custom font before it is used in the page.

Here are the steps to manage multiple custom fonts in Puppeteer:

1. Define and load each custom font using the FontFace API. You can create a function that takes the font URL, name, and weight as parameters, and returns a FontFace object.

function preloadFont(fontUrl, fontName, fontWeight) {
  const font = new FontFace(fontName, `url(${fontUrl})`, {
    weight: fontWeight
  });
  font.load();
  document.fonts.add(font);
}

1. Call the preloadFont function for each custom font you want to use in the page.

preloadFont('path-to-font/font1.woff2', 'CustomFont1', 400);
preloadFont('path-to-font/font2.woff2', 'CustomFont2', 400);

1. Once all custom fonts are preloaded, you can then use them in your page styles as usual.

body {
  font-family: 'CustomFont1', sans-serif;
}

h1 {
  font-family: 'CustomFont2', serif;
}

By preloading custom fonts using the FontFace API in Puppeteer, you ensure that the fonts are loaded and available before rendering the page, avoiding any delays or issues with font rendering.

What is the difference between locally hosted and web-hosted custom fonts in Puppeteer?

Locally hosted custom fonts are fonts that are stored on the user's computer or local server and are included in the Puppeteer script using the font-family property in CSS. These fonts are available only to the users who have the font installed on their system or have access to the local server where the font is hosted.

On the other hand, web-hosted custom fonts are fonts that are hosted on a web server and are accessed by the Puppeteer script using a URL provided by the font provider. These fonts are loaded dynamically from the web server when the page is rendered, ensuring that all users have access to the custom font, regardless of whether it is installed on their system.

In summary, the main difference between locally hosted and web-hosted custom fonts in Puppeteer is the location of the font files and how they are accessed by the script. Local fonts are restricted to users who have the font installed locally or have access to the server hosting the font, while web-hosted fonts are accessible to all users as they are loaded from a web server.

What is the process for integrating Google Fonts with Puppeteer on an Ubuntu server?

To integrate Google Fonts with Puppeteer on an Ubuntu server, you can follow these steps:

1. Install Puppeteer: First, install Puppeteer on your Ubuntu server by running the following command: npm install puppeteer
2. Install necessary packages: Install the necessary font-related packages on your Ubuntu server by running the following command: sudo apt-get install -y fonts-ipafont-gothic fonts-wqy-zenhei fonts-thai-tlwg fonts-kacst ttf-freefont
3. Include Google Fonts in your Puppeteer script: In your Puppeteer script, you can use the following code to load and use Google Fonts: const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('https://yourwebsite.com'); await page.evaluate(() => { const link = document.createElement('link'); link.href = 'https://fonts.googleapis.com/css2?family=Roboto'; link.rel = 'stylesheet'; document.head.appendChild(link); document.body.style.fontFamily = 'Roboto, sans-serif'; }); await page.screenshot({ path: 'screenshot.png' }); await browser.close();
4. Run the Puppeteer script: Save your Puppeteer script with the Google Fonts integration and run it on your Ubuntu server using Node.js.

By following these steps, you can integrate Google Fonts with Puppeteer on your Ubuntu server.
