## Install

```sh

npm install fib-pool [--save]

```

## Test

```sh

npm run ci

```

## Creating a pool

Simple example.

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool(() => {

    return db.open("sqlite:test.db");

});

```

Specify maxsize and timeout.

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool(() => {

    return db.open("sqlite:test.db");

}, 10, 30 * 1000);

```

Specify custom destroy function.

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool({

    create: () => {

        return db.open("sqlite:test.db");

    },

    destroy: (o) => {

        o.close()

    },

    timeout: 30 * 1000,

    retry: 3

});

```

## Using the pool

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool({

    create: () => {

        return db.open("sqlite:test.db");

    },

    destroy: (o) => {

        o.close()

    },

    timeout: 30 * 1000,

    retry: 3

});

var res = p((conn) => {

    conn.execute("select * from test");

});

```

## Using the pool with name

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool({

    create: (name) => {

        return db.open("sqlite:" + name + ".db");

    },

    destroy: (o) => {

        o.close()

    },

    timeout: 30 * 1000

});

var res = p("test", (conn) => {

    conn.execute("select * from test");

});

```

## Clear a pool

Simple example.

```js

var db = require("db");

var Pool = require("fib-pool");

var p = Pool(() => {

    return db.open("sqlite:test.db");

});

p.clear();

```
