Nginx config for svelte SPA, SSR turned off

 Nginx Config for Svelte SPA with SSR Turned Off


Introduction


When it comes to developing single-page applications (SPAs) with server-side rendering (SSR) turned off, one popular choice among developers is Svelte. Known for its simplicity and lightweight nature, Svelte offers a great framework for building efficient and fast web applications. In this article, we will explore how to configure Nginx to serve a Svelte SPA with SSR turned off, ensuring optimal performance and smooth user experience.


Prerequisites


Before we dive into the Nginx configuration, let's make sure you have the following prerequisites in place:


A server or hosting environment with Nginx installed.


A built and bundled version of your Svelte application.


A domain or subdomain configured to point to your server's IP address.


Nginx Configuration Steps


Now, let's proceed with the necessary configuration steps to serve your Svelte SPA through Nginx:


Step 1: Create a New Server Block


Open your Nginx configuration file, which is commonly located at /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf. Inside this file, create a new server block by adding the following code:


server { listen 80; # Replace with the appropriate port if using a different one server_name yourdomain.com; # Replace with your actual domain or subdomain root /path/to/your/svelte/app; index index.html; location / { try_files $uri $uri/ /index.html; } }

Make sure to replace yourdomain.com with your actual domain or subdomain and /path/to/your/svelte/app with the path to your Svelte application's built directory.


Step 2: Configure the Server Block


Now, let's go through each section of the server block to understand its purpose:


listen: Specifies the port on which Nginx should listen for incoming HTTP requests. Modify this if your application is running on a different port.


server_name: Defines the domain or subdomain that this server block will handle.


root: Indicates the root directory where your Svelte application's built files are located.


index: Specifies the default file to serve when the URL path does not include a specific file.


location /: Handles requests for the root URL or any other URL path within the Svelte application. The try_files directive attempts to locate the requested file; if it doesn't exist, it falls back to serving index.html.


Step 3: Save and Restart Nginx


After making the necessary changes to the Nginx configuration file, save the file and exit. Now, restart Nginx to apply the changes by running the following command:


sudo service nginx restart

Verifying the Configuration


To ensure that your Nginx configuration is working correctly, follow these steps:


Open a web browser and enter your domain or subdomain in the address bar.


If everything is set up correctly, your Svelte SPA should load without any issues. Verify that all the functionalities of your application are working as expected.


Conclusion


Congratulations! You have successfully configured Nginx to serve your Svelte SPA with SSR turned off. By following the provided steps, you can ensure optimal performance and deliver your web application seamlessly to your users. Enjoy building amazing Svelte SPAs and providing exceptional user experiences.


Remember to keep your Nginx configuration updated if you make changes to your Svelte application's build output in the future. This will guarantee that your users always get the latest version of your application when they visit your domain or subdomain.


Happy coding!

bad character U+002D '-' in my helm template

 In Helm templates, the hyphen character (`-`) can sometimes be treated as a reserved character, particularly when defining values or labels. To include a hyphen character in a Helm template without issues, you can use one of the following approaches: 1. **Quoting the Hyphen:**    You can enclose the hyphen in double quotes, like this:    ```yaml    key: "-"    ```    This way, Helm will interpret the hyphen as a string rather than an operator. 2. **Using Backticks:**    If you need to use the hyphen within a Go template function or inside backticks, you can escape it with a backslash (`\`), like this:    ```yaml    value: `{{ .Values.someField | printf "%s \\-" }}`    ```    The backslash prevents Helm from interpreting the hyphen as a special character. 3. **Variable Assignment:**    Assign the value to a variable and use it. For example:    ```yaml    {{- $hyphen := "-" }}    key: {{ $hyphen }}    ```    This way, you can use the variable `$hyphen` wher

GitLab pipeline stopped working with invalid yaml error

 When your GitLab pipeline has stopped working with an "invalid YAML" error, it means there's a problem with your `.gitlab-ci.yml` file. This could be due to syntax errors, incorrect indentation, or other issues in your pipeline configuration. Here's how to troubleshoot and resolve this issue: 1. **Check for Syntax Errors**:    Carefully review your `.gitlab-ci.yml` file for any syntax errors. Common issues include missing colons, indentation problems, or mismatched quotation marks. Use a YAML linter or an online YAML validator to identify and correct syntax errors. 2. **Indentation**:    YAML relies heavily on proper indentation. Make sure that all lines within the same block have consistent indentation (typically using spaces, not tabs). Incorrect indentation can cause YAML parsing errors. 3. **Dashes and Lists**:    Ensure that you use the correct syntax for lists (arrays) in YAML by starting each item with a dash (`-`). Be consistent with your use of dashes throug

How do I add a printer in OpenSUSE which is being shared by a CUPS print server?

 To add a printer in openSUSE that is being shared by a CUPS print server, you can use the following steps: 1. **Ensure CUPS Client is Installed:**    Make sure your openSUSE system has the CUPS client tools installed. You can install them using the following command:    ```bash    sudo zypper install cups-client    ``` 2. **Discover Available Printers:**    Use the `lpinfo` command to discover available printers on your CUPS print server. Replace `cups-server-hostname` with the hostname or IP address of your CUPS server:    ```bash    lpinfo -v -h cups-server-hostname:631    ```    This command should list the printers shared by the CUPS server. 3. **Add a Printer:**    Use the `lpadmin` command to add a printer. Replace `printer-name` with the name of the printer you want to add and `printer-uri` with the URI obtained from the `lpinfo` command:    ```bash    sudo lpadmin -p printer-name -E -v printer-uri    ```    For example:    ```bash    sudo lpadmin -p MyPrinter -E -v socket://cu
