`--dump` formats the page output without writing JavaScript.
```bash
obscura fetch https://example.com --dump html
obscura fetch https://example.com --dump text
obscura fetch https://example.com --dump markdown
obscura fetch https://example.com --dump links
obscura fetch https://example.com --dump assets
obscura fetch https://example.com --dump original
obscura fetch https://example.com --dump cookies
```
## `html`
Rendered HTML after JavaScript runs. Default.
```bash
obscura fetch https://news.ycombinator.com --dump html > hn.html
```
## `text`
Plain text. No markup.
```bash
obscura fetch https://en.wikipedia.org/wiki/Rust_(programming_language) --dump text
```
## `markdown`
Markdown conversion: headings, lists, links, code blocks, images.
```bash
obscura fetch https://docs.example.com/page --dump markdown > page.md
```
## `links`
Every `<a href>` on the page, one per line.
```bash
obscura fetch https://example.com --dump links
```
## `assets`
Every external resource (stylesheets, scripts, images, fonts, iframes), plus the URLs the page requested through `fetch()`/XHR, one JSON object per line.
```bash
obscura fetch https://example.com --dump assets
```
## `original`
The raw HTML the server sent, before JavaScript ran.
```bash
obscura fetch https://my-spa.example --dump original > before.html
obscura fetch https://my-spa.example --dump html > after.html
diff before.html after.html
```
## `cookies`
Every cookie in the jar as a JSON array, including HttpOnly cookies that `document.cookie` cannot see. Useful for capturing session tokens set by anti-bot challenges.
```bash
obscura fetch https://example.com --dump cookies
```
## With `--wait-until`
`--dump` runs after the wait condition:
```bash
obscura fetch https://my-spa.example --wait-until load --dump markdown
```
## Pipe and redirect
```bash
obscura fetch https://example.com --dump markdown > example.md
obscura fetch https://example.com --dump text --quiet | wc -w
```
