# BaraDB JavaScript / Node.js Client
Official JavaScript client for **BaraDB** — a multimodal database engine written in Nim.
## Features
- **Binary wire protocol** — fast TCP communication
- **Promise-based API** — modern async/await
- **Query builder** — fluent SQL construction
- **Parameterized queries** — safe from SQL injection
- **Vector & JSON support** — first-class multimodal types
- **TypeScript definitions** — included out of the box
## Installation
```bash
npm install baradb
```
Or from source:
```bash
git clone https://github.com/barabadb/baradadb.git
cd clients/javascript
npm link
```
## Quick Start
```javascript
const { Client } = require('baradb');
async function main() {
const client = new Client('localhost', 9472);
await client.connect();
const result = await client.query("SELECT name, age FROM users WHERE age > 18");
for (const row of result) {
console.log(row.name, row.age);
}
await client.close();
}
main().catch(console.error);
```
### Parameterized Queries
```javascript
const { Client, WireValue } = require('baradb');
async function main() {
const client = new Client('localhost', 9472);
await client.connect();
const result = await client.queryParams(
'SELECT * FROM users WHERE age > $1 AND country = $2',
[WireValue.int64(18), WireValue.string('BG')]
);
for (const row of result) {
console.log(row);
}
await client.close();
}
```
### Query Builder
```javascript
const { Client, QueryBuilder } = require('baradb');
async function main() {
const client = new Client('localhost', 9472);
await client.connect();
const result = await new QueryBuilder(client)
.select('name', 'email')
.from('users')
.where('active = true')
.orderBy('name')
.limit(10)
.exec();
for (const row of result) {
console.log(row);
}
await client.close();
}
```
### Vector Search
```javascript
const { Client, WireValue } = require('baradb');
async function main() {
const client = new Client('localhost', 9472);
await client.connect();
const result = await client.queryParams(
'SELECT id, name FROM products ORDER BY embedding <-> $1 LIMIT 5',
[WireValue.vector([0.1, 0.2, 0.3])]
);
await client.close();
}
```
## Running Tests
Unit tests (no server):
```bash
npm run test:unit
```
Integration tests (requires server on `localhost:9472`):
```bash
# Start server
docker run -d -p 9472:9472 baradb:latest
# Run integration tests
npm run test:integration
# Run all tests
npm test
```
## API Reference
### `new Client(host, port, options)`
| Option | Default | Description |
|--------------|-------------|----------------------------|
| `host` | `localhost` | Server hostname |
| `port` | `9472` | TCP wire protocol port |
| `database` | `default` | Default database |
| `username` | `admin` | Username |
| `password` | `""` | Password |
| `timeout` | `30000` | Socket timeout in ms |
### Methods
- `connect()` — open TCP connection
- `close()` — close connection
- `query(sql)` — execute SELECT-like query
- `queryParams(sql, params)` — parameterized query
- `execute(sql)` — execute DDL/DML, returns affected rows
- `auth(token)` — JWT authentication
- `ping()` — health check

# BaraDB Nim Client
Official Nim client for **BaraDB** — a multimodal database engine.
## Features
- **Binary wire protocol** — fast TCP communication via `asyncnet`
- **Async/await API** — non-blocking by default
- **Sync wrapper** — `SyncClient` for blocking code
- **Query builder** — fluent SQL construction
- **Zero server dependencies** — self-contained, uses only Nim stdlib
## Installation
Add to your `.nimble` file:
```nim
requires "baradb >= 1.0.0"
```
Or clone locally:
```bash
git clone https://github.com/barabadb/baradadb.git
cd clients/nim
nimble develop
```
## Quick Start
### Async API
```nim
import asyncdispatch
import baradb/client
proc main() {.async.} =
let client = newClient()
await client.connect()
let result = await client.query("SELECT name, age FROM users WHERE age > 18")
echo result
client.close()
waitFor main()
```
### Sync API
```nim
import baradb/client
let client = newSyncClient()
client.connect()
let result = client.query("SELECT name, age FROM users WHERE age > 18")
echo result
client.close()
```
### Parameterized Queries
```nim
import baradb/client
proc main() {.async.} =
let client = newClient()
await client.connect()
let result = await client.query(
"SELECT * FROM users WHERE age > $1",
@[WireValue(kind: fkInt64, int64Val: 18)]
)
echo result
client.close()
waitFor main()
```
### Query Builder
```nim
import baradb/client
proc main() {.async.} =
let client = newClient()
await client.connect()
let result = await newQueryBuilder(client)
.select("name", "email")
.from("users")
.where("active = true")
.orderBy("name", "ASC")
.limit(10)
.exec()
echo result
client.close()
waitFor main()
```
## Running Tests
Unit tests (no server):
```bash
nimble test
```
Integration tests (requires server on `localhost:9472`):
```bash
# Start server
docker run -d -p 9472:9472 baradb:latest
# Run integration tests
nim c -r tests/test_integration.nim
```
## API Reference
### `ClientConfig`
| Field | Default | Description |
|--------------|-------------|------------------------|
| `host` | `127.0.0.1` | Server hostname |
| `port` | `9472` | TCP port |
| `database` | `default` | Default database |
| `username` | `admin` | Username |
| `password` | `""` | Password |
| `timeoutMs` | `30000` | Timeout in ms |
| `maxRetries` | `3` | Max reconnect retries |
### Methods (Async)
- `connect()` — open TCP connection
- `close()` — close connection
- `query(sql)` — execute SELECT-like query
- `query(sql, params)` — parameterized query
- `exec(sql)` — execute DDL/DML, returns affected rows
- `auth(token)` — JWT authentication
- `ping()` — health check
### Methods (Sync)
Same as async but blocking. Available on `SyncClient`.

# BaraDB Python Client
Official Python client for **BaraDB** — a multimodal database engine written in Nim.
## Features
- **Binary wire protocol** — fast, compact TCP communication
- **Sync & blocking API** — simple to use in scripts and apps
- **Query builder** — fluent SQL construction
- **Parameterized queries** — safe from SQL injection
- **Vector & JSON support** — first-class multimodal types
- **Context managers** — `with` statement support
## Installation
```bash
pip install baradb
```
Or from source:
```bash
git clone https://github.com/barabadb/baradadb.git
cd clients/python

.order_by("name")
.limit(10)
)
result = qb.exec()
for row in result:
print(row)
```
### Vector Search
```python
from baradb import Client, WireValue
with Client("localhost", 9472) as client:
result = client.query_params(
"SELECT id, name FROM products ORDER BY embedding <-> $1 LIMIT 5",
[WireValue.vector([0.1, 0.2, 0.3])],
)
```
## Running Tests
Unit tests (no server):
```bash
pytest tests/test_wire_protocol.py tests/test_query_builder.py

pytest
```
## API Reference
### `Client(host, port, database, username, password, timeout)`
| Parameter | Default | Description |
|------------|-------------|----------------------------|
| `host` | `localhost` | Server hostname |
| `port` | `9472` | TCP wire protocol port |
| `database` | `default` | Default database |
| `username` | `admin` | Username |
| `password` | `""` | Password |
| `timeout` | `30` | Socket timeout in seconds |
### Methods
- `connect()` — open TCP connection
- `close()` — close connection
- `query(sql) -> QueryResult` — execute SELECT-like query
- `query_params(sql, params) -> QueryResult` — parameterized query
- `execute(sql) -> int` — execute DDL/DML, returns affected rows

# BaraDB Rust Client
Official Rust client for **BaraDB** — a multimodal database engine written in Nim.
## Features
- **Binary wire protocol** — fast TCP communication using only `std`
- **Zero dependencies** — no external crates required
- **Sync API** — blocking I/O suitable for most applications
- **Query builder** — fluent SQL construction
- **Vector & JSON support** — first-class multimodal types
## Installation
Add to your `Cargo.toml`:
```toml
[dependencies]
baradb = "1.0"
```
Or from source:
```bash
git clone https://github.com/barabadb/baradadb.git
cd clients/rust
cargo build
```
## Quick Start
```rust
use baradb::Client;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut client = Client::connect("localhost", 9472)?;
let result = client.query("SELECT name, age FROM users WHERE age > 18")?;
for row in result.rows() {
println!("{:?}", row);
}
client.close();
Ok(())
}
```
### Parameterized Queries
```rust
use baradb::{Client, WireValue};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut client = Client::connect("localhost", 9472)?;
let result = client.query_params(
"SELECT * FROM users WHERE age > $1 AND country = $2",
&[WireValue::Int64(18), WireValue::String("BG".to_string())],
)?;
for row in result.rows() {
println!("{:?}", row);
}
client.close();
Ok(())
}
```
### Query Builder
```rust
use baradb::Client;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut client = Client::connect("localhost", 9472)?;
let result = baradb::QueryBuilder::new(&mut client)
.select(&["name", "email"])
.from("users")
.where_clause("active = true")
.order_by("name", "ASC")
.limit(10)
.exec()?;
for row in result.rows() {
println!("{:?}", row);
}
client.close();
Ok(())
}
```
### Vector Search
```rust
use baradb::{Client, WireValue};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut client = Client::connect("localhost", 9472)?;
let result = client.query_params(
"SELECT id, name FROM products ORDER BY embedding <-> $1 LIMIT 5",
&[WireValue::Vector(vec![0.1, 0.2, 0.3])],
)?;
client.close();
Ok(())
}
```
## Running Tests
Unit tests (no server):
```bash
cargo test --lib
```
Integration tests (requires server on `localhost:9472`):
```bash
# Start server
docker run -d -p 9472:9472 baradb:latest
# Run all tests
cargo test
```
## API Reference
### `Client::connect(host, port)`
Creates a new client connected to the given host and port.
### Methods
- `query(sql) -> Result<QueryResult>` — execute SELECT-like query
- `query_params(sql, params) -> Result<QueryResult>` — parameterized query
- `execute(sql) -> Result<usize>` — execute DDL/DML, returns affected rows
- `auth(token) -> Result<()>` — JWT authentication
- `ping() -> Result<bool>` — health check
- `close()` — close connection
