## What is Stapler

Stapler is a **static page delivery server**.

You feed it a <u>tar.gz</u> file of your content, and it serves it at your desired path or host.

It handles:

* static files delivery: `/path/xxx`
* directory roots translation into `index.html` (if existing)
* host translation to specific path: `my.example.com => /path/`
* auto host discovery and certificate issuing (via certbot)
* redirect pages: `/path-2/ => (redirect) https://my-website.com`
* proxy pages: `/path-3/ => https://my-website.com`
* updating/deleting content via API with `curl`

## Python CLI

### Basic usage

Theres 3 basic commands for the stapler server:

* `run`: launch the server to serve at the desired paths (see full CLI help for env vars and such)
* `renew`: renew all existing certificates (the server must be running in the background)
* `token`: generate a new secure API token

See [Docker](#docker) for a quick deployable server.

## HTTP API

### Create/update page from gzip

```txt
PUT /{page}/
  X-Token (your API token)
  X-Host (optional host as entrypoint)
  (body with tar data)
```

```bash
# create archive from 'dist' dir and upload it to /my-project/
tar -czC dist -f dist.tar.gz .
curl -X PUT \
  -H 'X-Token: <TOKEN>' \
  --data-binary "@dist.tar.gz" \
  https://stapler-host/my-project/

# same thing but one-liner
tar -czC dist . | curl -X PUT \
  -H 'X-Token: <TOKEN>' \
  --data-binary @- \
  https://stapler-host/my-project/

# make stapler server identifiers myproject.example.com as /my-project/
tar -czC dist . | curl -X PUT \
  --data-binary @- \
  -H 'X-Token: <TOKEN>' \
  -H 'X-Host: myproject.example.com' \
  https://stapler-host/my-project/
```

### Create/update page with redirect

```txt
PUT /{page}/
  X-Token (your API token)
  X-Redirect (redirection target)
  X-Host (optional host as entrypoint)
```

```bash
# create /my-project/ that redirects to https://github.com/my-project
curl -X PUT \
  -H 'X-Token: <TOKEN>' \
  -H 'X-Redirect: https://github.com/my-project' \
  https://stapler-host/my-project/

# simple redirect from root host to www
curl -X PUT \
  -H 'X-Token: <TOKEN>' \
  -H 'X-Proxy: https://www.my-website.com' \
  -H 'X-Host: my-website.com' \
  https://stapler-host/my-website-www/
```

### Create/update page with proxy

```txt
PUT /{page}/
  X-Token (your API token)
  X-Proxy (proxy target)
  X-Host (optional host as entrypoint)
```

```bash
# create /my-website/ that proxies to http://localhost:8000
curl -X PUT \
  -H 'X-Token: <TOKEN>' \
  -H 'X-Proxy: http://localhost:8000' \
  https://stapler-host/my-project/
```

### Delete page

```txt
DELETE /{page}/
  X-Token (your API token)
```

```bash
# delete /my-project/
curl -X DELETE \
  -H 'X-Token: <TOKEN>' \
  https://stapler-host/my-project/
```

## Docker

Stapler ships with a deploy-ready `Dockerfile` and a sample `docker compose` stack with:

* a main server exposing on port 80 (http) and port 443 (https)
* a weekly crontab for updating certificates

```bash
cp crontab.example crontab
cp compose.example.yml compose.yml
cp .env.example .env
$EDITOR .env # update HOST and TOKEN_SALT
docker compose up
# whenever you need a new token
docker compose run --rm stapler token
```
