jasonisnthappy is available for Rust, Go, Python, and JavaScript (Node.js, Deno, and Bun). Choose your language below to get started.

​
Rust

For Rust projects, add jasonisnthappy as a dependency to your Cargo.toml: 
[dependencies]
jasonisnthappy = "0.1.1"
serde_json = "1.0"  # For JSON document handling

​
Features

jasonisnthappy supports optional features that can be enabled in your Cargo.toml:
Cargo.toml
[dependencies]
jasonisnthappy = { version = "0.1.1", features = ["web-ui"] }
FeatureDescriptionDefault
web-uiBuilt-in web interface and REST APIEnabled
The web-ui feature includes the tiny_http dependency for serving the dashboard. Disable it with default-features = false if you don’t need the web interface.

​
Platform support

  • macOS: ARM64 (Apple Silicon) and x86_64 (Intel)
  • Linux: ARM64 and x86_64
  • Windows: x86_64

​
Quick example

src/main.rs
use jasonisnthappy::core::database::Database;
use serde_json::json;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let db = Database::open("mydb.db")?;

    let mut tx = db.begin()?;
    let mut users = tx.collection("users");

    let user = json!({"name": "Alice", "age": 30});
    let id = users.insert(user)?;

    tx.commit()?;
    db.close()?;

    Ok(())
}

​
Go

For Go projects, jasonisnthappy uses CGO to link against native libraries. The libraries are automatically downloaded during installation.
1

Install the package

Terminal
go get github.com/sohzm/jasonisnthappy/bindings/go
2

Download native libraries

Terminal
go generate github.com/sohzm/jasonisnthappy/bindings/go
This downloads the pre-compiled static library (.a file) from GitHub releases and caches it in lib/<platform>/.
3

Build your application

Terminal
go build
Your binary is now fully self-contained with no external dependencies!
CGO must be enabled (which is the default). The native library is statically linked into your binary, so you get a single standalone executable with zero runtime dependencies.

​
Requirements

  • CGO enabled (default on most systems)
  • C compiler:
    • macOS: xcode-select --install
    • Linux: apt install build-essential or yum install gcc
    • Windows: Install MinGW-w64
  • Internet connection for first build (to download native library)

​
Platform support

  • macOS: ARM64 (Apple Silicon) and x86_64 (Intel)
  • Linux: ARM64 and x86_64
  • Windows: x86_64
Windows ARM64 is not currently supported.

​
Quick example

main.go
package main

import (
    "fmt"
    "log"

    db "github.com/sohzm/jasonisnthappy/bindings/go"
)

func main() {
    // Open database
    database, err := db.Open("./my_database.db")
    if err != nil {
        log.Fatal(err)
    }
    defer database.Close()

    // Begin transaction
    tx, err := database.BeginTransaction()
    if err != nil {
        log.Fatal(err)
    }
    defer tx.Rollback() // Auto-rollback if not committed

    // Insert document
    doc := map[string]interface{}{
        "name": "Alice",
        "age":  30,
        "email": "alice@example.com",
    }
    id, err := tx.Insert("users", doc)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("Inserted document with ID: %s\n", id)

    // Commit transaction
    err = tx.Commit()
    if err != nil {
        log.Fatal(err)
    }
}

​

​
Python

For Python projects, install jasonisnthappy via pip. The package automatically downloads the native library for your platform.
Terminal
pip install jasonisnthappy

​
Platform support

  • macOS: Intel and Apple Silicon
  • Linux: x86_64
  • Windows: x86_64
Pre-built binaries are provided for all supported platforms and are automatically downloaded from GitHub releases.

​
Quick example

main.py
from jasonisnthappy import Database

# Open database
db = Database.open("./my_database.db")

try:
    # Begin transaction
    tx = db.begin_transaction()

    try:
        # Get collection
        users = tx.collection("users")

        # Insert document
        doc_id = users.insert({
            "name": "Alice",
            "age": 30,
            "email": "alice@example.com"
        })
        print(f"Inserted document with ID: {doc_id}")

        # Find by ID
        user = users.find_by_id(doc_id)
        print(f"Found: {user}")

        # Commit transaction
        tx.commit()
    except Exception as e:
        # Rollback on error
        tx.rollback()
        raise
finally:
    db.close()

​
Using context managers

Python bindings support context managers for automatic resource cleanup:
main.py
from jasonisnthappy import Database

with Database.open("./my_database.db") as db:
    with db.begin_transaction() as tx:
        users = tx.collection("users")

        doc_id = users.insert({"name": "Alice", "age": 30})
        user = users.find_by_id(doc_id)
        print(user)

        # Transaction is automatically committed if no exception occurs
        # or rolled back if an exception is raised
Using context managers is the recommended approach as it ensures proper resource cleanup even if errors occur.

​
Type hints

The library includes full type hints for better IDE support:
main.py
from typing import Dict, Any, List
from jasonisnthappy import Database, Transaction, Collection

db: Database = Database.open("./my_database.db")
tx: Transaction = db.begin_transaction()
users: Collection = tx.collection("users")

doc: Dict[str, Any] = {"name": "Alice", "age": 30}
doc_id: int = users.insert(doc)

result: Dict[str, Any] | None = users.find_by_id(doc_id)
results: List[Dict[str, Any]] = users.query("age > 25")

index.ts
import { Database, Collection, Document } from '@sohzm/jasonisnthappy';

interface User extends Document {
  name: string;
  age: number;
  email: string;
}

const db = Database.open('./my_database.db');
const users: Collection<User> = db.getCollection<User>('users');

// Type-safe insert (no _id needed)
const id = users.insert({
  name: 'Alice',
  age: 30,
  email: 'alice@example.com'
});

// Type-safe query
const user: User | null = users.findById(id);
if (user) {
  console.log(user.name); // TypeScript knows this is a string
}

db.close();

​
Troubleshooting

​
Go: CGO errors

If you encounter CGO-related errors, ensure you have a C compiler installed:
  • macOS: xcode-select --install
  • Linux: apt install build-essential or yum install gcc
  • Windows: Install MinGW-w64

​
Go: Library download fails

  • Ensure you have internet connectivity
  • Check that the GitHub release exists with the required files
  • Verify your platform is supported (run go env GOOS GOARCH)

​
Python: Library not found

If the native library is not found, manually download it from the releases page and place it in the appropriate lib/ directory for your platform.

​
JavaScript: Platform not supported

The error indicates your platform is not supported. Currently supported:
  • macOS: darwin-arm64, darwin-amd64
  • Linux: linux-arm64, linux-amd64
  • Windows: windows-amd64

​
Database file corruption

If you suspect database corruption, jasonisnthappy includes built-in corruption detection in the LRU page cache. You can verify a backup file using: 
use jasonisnthappy::Database;

let backup_info = Database::verify_backup("backup.db")?;
println!("Backup version: {}", backup_info.version);
println!("Collections: {:?}", backup_info.collections);
