# warmer
A CDN cache warmer in rust for the sitemap.xml files that look like this:

```xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/sitemap.xsl"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/1999/xhtml">
<url>
    <loc>https://abh.ai/</loc>
    <lastmod>2022-06-25T20:46Z</lastmod>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
</url>

## Usage

Download (from [here](https://github.com/codingsasi/warmer/releases)) and run the executable binary on linux with the following command
```
warmer http(s)://someurl.com interl
 - ./warmer https://abh.ai 5
 - ./warmer https://abh.ai 1
```
- The interval value should be specified in seconds, and it's how long the warmer waiting before loading the next URL in the sitemap.
- The default interval is 5 seconds. No interval (0s) is allowed but use only if you want to DDOS your own site.
- The complete url should be specified with scheme as well.

### Build from source
1. Clone the repo
2. cd warmer
3. Install cargo https://doc.rust-lang.org/cargo/getting-started/installation.html
4. cargo build --release
5. The binary will be in the target/release folder. It will also be named `warmer`
6. You may need to install `libudev-dev`, `libssl-dev`, `openssl`, `pkg-config`, `build-essential`.

### Running using docker
1. docker pull abhaisasidharan/warmer 
2. docker run abhaisasidharan/warmer -it warmer https://abh.ai 5

### Notes
Large sitemaps, that include other zipped or gzipped sitemaps are not supported yet. I'll release that as and when I get time. But for most sitemaps this should warm it just fine.
Currently on supported on 64-bit linux OS.
