# How to contribute
Hermes is still in a developmental phase. Helping with test cases, benchmarks, speed, and memory usage are a great way to contribute to the project.

## Hermes Go
Direct access to the hermes cache/nocache functions.
```
go get github.com/realTristan/hermes
```

## Hermes Cloud
Access the hermes cache functions via websocket.

### Python
```
pip install hermescloud
```

# What is Hermes?
Hermes is an extremely fast full-text search and caching framework written in Go.
Hermes has a cache algorithm where you can set, get, store, etc. keys and values into the cache, and a no-cache algorithm that reads data from an array or json file and uses an array to store data. Both of these algorithms provide full-text search query speeds from 10µs to 300µs.

# Example of NoCache
If you want to use only the full-text-search features, then import hermes/nocache. Load the data using a .json file or array of maps. No Cache is much faster than the With-Cache algorithm, but you can't update the data.

## Code
```go
package main

import (
"fmt"
"time"

hermes "github.com/realTristan/hermes/nocache"
)

func main() {
// Initialize the full-text cache
var ft, _ = hermes.InitWithJson("data.json")

// Search for a word in the cache
var res, _ = ft.Search(hermes.SearchParams{
Query: "tristan",
Limit: 100,
Strict: false,
})

fmt.Println(res)
}
```

### Benchmarks
```
Dataset Map Entries: 4,115
Dataset Total Words: 208,092
Dataset Map Size: ≈ 2.3MB

Query: Computer, Limit: 100, Strict: False => 36.5µs
Query: Computer, Limit: 100, Strict: True => 12.102µs
```

### data.json
Used with hermes.InitWithJson()
```json
[
{
"id": 1,
"name": {
"$hermes.full_text": true,
"$hermes.value": "Tristan Simpson"
},
},
]
```

# With-Cache Example
The with-cache algorithm is notably slower than the no-cache algorithm. Why? Because the with-cache algorithm uses maps to store data and not an array. Import hermes directly to use the with-cache features.

## Code
```go
package main

import (
"fmt"
"time"
hermes "github.com/realTristan/hermes"
)

func main() {
// Initialize the cache
cache := hermes.InitCache()

// MaxSize: 10, MaxBytes: -1 (no limit), MinWordLength: 3
cache.FTInit(10, -1, 3)

// Set the value in the cache
cache.Set("user_id", map[string]any{
"name": cache.WithFT("tristan"),
"age": 17,
})

// Search for a word in the cache and print the result
result, err := cache.Search(hermes.SearchParams{
Query: "tristan",
Limit: 100,
Strict: false,
})

fmt.Println(result)
}
```

### Benchmarks
```
Dataset Map Entries: 4,115
Dataset Total Words: 208,092
Dataset Map Size: ≈ 2.3MB

Query: Computer, Limit: 100, Strict: False => 263.7µs
Query: Computer, Limit: 100, Strict: True => 40.84µs
```

### data.json
Used with cache.FTInitWithJson()
```json
{
"user_id": {
"age": 17,
"name": {
"$hermes.full_text": true,
"$hermes.value": "Tristan Simpson"
},
},
}
```

# Hermes Cloud App
## Install
```
Coming Soon
```

## Custom Implementation
```go
import (
"github.com/gofiber/fiber/v2"
hermes "github.com/realTristan/hermes"
socket "github.com/realTristan/hermes/cloud/socket"
)

func main() {
// Cache and fiber app
cache := hermes.InitCache()
app := fiber.New()

// Set the router
socket.SetRouter(app, cache)

// Listen on port 3000
app.Listen(":3000")
}
```
