README
# [](https://github.com/ttytm/vibe)
Vibe is a request library that wraps libcurl to enable fast and reliable requests while providing a
higher-level API.
## Installation
**Development- / Build Dependencies**
- libcurl - E.g., on Debian-based Linux distros, this might be `libcurl4-openssl-dev` or
`libcurl4-gnutls-dev`.
**Vibe as V module**
- Install via V's cli
```sh
# Into `/vibe`
v install https://github.com/ttytm/vibe
# OR as vpm module under a namespace `/ttytm/vibe`
v install ttytm.vibe
```
## Usage examples
#### GET request
> **NOTE**
> For installations as VPM module use
>
> ```v
> import ttytm.vibe
> ```
```v
import vibe
// Default request
resp := vibe.get('https://hacker-news.firebaseio.com/v0/item/1.json')!
println(resp.body)
// Custom request
request := vibe.Request{
headers: {
.user_agent: 'YourCustomUserAgent/v0.0.1'
}
}
resp2 := request.get('https://hacker-news.firebaseio.com/v0/item/1.json')!
println(resp2.body)
```
[`get_test`](https://github.com/ttytm/vibe/blob/main/src/_tests_get_test.v)
#### POST request
```v
import vibe
import time
req := vibe.Request{
headers: {
.user_agent: 'YourCustomUserAgent/v0.0.1'
.content_type: 'application/json; charset=utf-8'
}
timeout: time.second * 10
}
resp := req.post('https://httpbin.org/post', '{"msg":"hello from vibe"}')!
println(resp)
```

#### Download
```v
import vibe
vibe.download_file('https://github.com/vlang/v/releases/download/weekly.2023.23/v_linux.zip',
'v_linux.zip')!
```

More examples
#### GET Slice request
If optimizing speed is of concern when querying pages with large response bodies, and you know you
only need a portion of them, you can perform a `get_slice` request.
```v oksyntax
// Sends a GET request to the specified `url` and returns a slice of the response content.
// Allocation of the received response as a vstring is postponed until the `start` byte position is reached.
// The content is returned as soon as the slice reaches its `max_size` (offset from `start`)
// - `max_size` can be `none` to return the remainder from the start.
pub fn (req Request) get_slice(url string, start usize, max_size ?usize) !Response
```
```v
import vibe
import net.html
resp := vibe.get_slice('https://docs.vosca.dev/advanced-concepts/v-and-c.html', 65_000,
10_000)!
selector := html.parse(resp.body).get_tags_by_class_name('language-vmod')[0]
println(selector.text())
```
[`get_slice_test`](https://github.com/ttytm/vibe/blob/main/src/_tests_get_slice_test.v)
#### Download with progress
```v oksyntax
// Downloads a document from the specified `url` and saves it to the specified `file_path`.
// `download` must implement a `progress(pos usize, size usize)`, and a `finish()` method.
pub fn (req Request) download_file_with_progress(url string, file_path string, download Download) !Response
```
```v
import vibe
import os
// User-defined struct that implements the `Download` interface.
struct MyStruct {
foo string
bar string
}
fn (dl MyStruct) progress(pos u64, size u64) {
print('\rDownloading... ${f64(pos) / size * 100:.2f}%')
os.flush()
}
fn (dl MyStruct) finish() {
println('\nDownload completed.')
}
mut download := MyStruct{}
vibe.download_file_with_progress('https://github.com/vlang/v/releases/download/weekly.2023.23/v_linux.zip',
'v_linux.zip', mut download)!
```
#### Persistent Cookie
Share cookies between requests / sessions with a curl cookie jar file.
The demo below does not provide real authentication data, for a "full" use-case scenario,
change the payload data and requested URLs to actual addresses that require authentication.
```v
import vibe
import os
cookie_jar := './demo_cookie'
req := vibe.Request{
headers: {
.content_type: 'application/json; charset=utf-8'
}
cookie_jar: cookie_jar
}
// Login and save cookies to curl cookie file.
req.post('https://api.yourdomain.com/v1/login', '{"username":"yourname","password":"password"}')!
// Use the `cookie_file` in subsequent sessions to access endpoints that require the authentication above.
req2 := vibe.Request{
headers: {
.content_type: 'application/json; charset=utf-8'
}
cookie_file: cookie_jar
}
resp := req2.get('https://api.yourdomain.com/v1/protected_page')!
// ... use resp
// Remove the cookie file or keep it for later usage.
os.rm(cookie_jar)!
```
## Further information and upcoming features
Vibe is in early development. Additional features will be added based on personal projects and
sensible community needs.
### Planned
- [x] Download with progress
- [x] Custom headers
- [x] Proxy support
- [ ] SSL options
- [ ] Extend HTTP methods
### Considered
- Additional curl-compatible formats beyond HTTP.
- Expose response streams / io.Reader implementation
- Support multiple curl versions / allow to opt into newer versions.
