One day you may want to replace the standard error pages of your HTTP server with something more original and pretty. That's what this repository was created for :) It contains:
- Simple error pages generator, written in Go
- Single-page error page templates with different designs (located in the [templates](https://github.com/tarampampam/error-pages/tree/master/templates) directory)
- Fast and lightweight HTTP server
- Already generated error pages (sources can be [found here][preview-sources], the **demonstration** is always accessible [here][preview-demo])
## ๐ฅ Features list
- HTTP server written in Go, with the extremely fast [FastHTTP][fasthttp] under the hood
- Respects the `Content-Type` HTTP header (and `X-Format`) value and responds with the corresponding format (supported formats are `json` and `xml`)
- Writes logs in `json` format
- Contains healthcheck endpoint (`/healthz`)
- Contains metrics endpoint (`/metrics`) in Prometheus format
- Lightweight docker image _(~4.6Mb compressed size)_, distroless and uses the unleveled user by default
- [Go-template](https://pkg.go.dev/text/template) tags are allowed in the templates
- Ready for integration with [Traefik][traefik] ([error pages customization](https://doc.traefik.io/traefik/middlewares/http/errorpages/)) and [Ingress-nginx][ingress-nginx]
- Error pages can be [embedded into your own `nginx`][wiki-usage-with-nginx] docker image
- Fully configurable (take a look at the [configuration file](https://github.com/tarampampam/error-pages/blob/master/error-pages.yml) and [project Wiki][wiki])
- Distributed using docker image and compiled binary files
- Localized (๐บ๐ธ, ๐ซ๐ท, ๐บ๐ฆ, ๐ท๐บ, ๐ต๐น, ๐ณ๐ฑ, ๐ฉ๐ช, ๐ช๐ธ, ๐จ๐ณ, ๐ฎ๐ฉ, ๐ต๐ฑ) HTML error pages (translation process [described here](https://github.com/tarampampam/error-pages/tree/master/l10n) - other translations are welcome!)
## ๐งฉ Install
Download the latest binary file for your os/arch from the [releases page][releases] or use our docker image:
| Registry | Image |
|-----------------------------------|-----------------------------------|
| [Docker Hub][docker-hub] | `tarampampam/error-pages` |
| [GitHub Container Registry][ghcr] | `ghcr.io/tarampampam/error-pages` |
> Using the `latest` tag for the docker image is highly discouraged because of possible backward-incompatible changes during **major** upgrades. Please, use tags in `X.Y.Z` format
๐ฃ **Or** you can download **already rendered** error pages pack as a [zip][pages-pack-zip] or [tar.gz][pages-pack-tar-gz] archive.

## ๐ Usage
Please, take a look at [our Wiki][wiki] for the common usage stories:
- [HTTP server][wiki-http-server] (routes, formats, flags and environment variables)
- [Pages generator][wiki-generator] (build your own error page set)
- [Static error pages][wiki-static-error-pages] (extract generated static error pages from the docker image)
- [Usage with nginx][wiki-usage-with-nginx] (include our error pages into an image with nginx)
- [Usage with Traefik and local Docker Compose][wiki-traefik-docker-compose] (it's a good starting point for the tests)
- [Usage with Traefik and Docker Swarm][wiki-traefik-swarm]
- [Kubernetes & ingress nginx][wiki-k8s-ingress-nginx]
