# better-sqlite3 [![Build Status](https://github.com/JoshuaWise/better-sqlite3/actions/workflows/build.yml/badge.svg)](https://github.com/JoshuaWise/better-sqlite3/actions/workflows/build.yml?query=branch%3Amaster)
The fastest and simplest library for SQLite in Node.js.
- Full transaction support
- High performance, efficiency, and safety
- Easy-to-use synchronous API *(better concurrency than an asynchronous API... yes, you read that correctly)*
- Support for user-defined functions, aggregates, virtual tables, and extensions
- 64-bit integers *(invisible until you need them)*
- Worker thread support *(for large/slow queries)*
## Help this project stay strong! &#128170;
`better-sqlite3` is used by thousands of developers and engineers on a daily basis. Long nights and weekends were spent keeping this project strong and dependable, with no ask for compensation or funding, until now. If your company uses `better-sqlite3`, ask your manager to consider supporting the project:
- [Become a GitHub sponsor](https://github.com/sponsors/JoshuaWise)
- [Become a backer on Patreon](https://www.patreon.com/joshuawise)
- [Make a one-time donation on PayPal](https://www.paypal.me/joshuathomaswise)
## How other libraries compare
| |select 1 row &nbsp;`get()`&nbsp;|select 100 rows &nbsp;&nbsp;`all()`&nbsp;&nbsp;|select 100 rows `iterate()` 1-by-1|insert 1 row `run()`|insert 100 rows in a transaction|
|---|---|---|---|---|---|
|better-sqlite3|1x|1x|1x|1x|1x|
|[sqlite](https://www.npmjs.com/package/sqlite) and [sqlite3](https://www.npmjs.com/package/sqlite3)|11.7x slower|2.9x slower|24.4x slower|2.8x slower|15.6x slower|
> You can verify these results by [running the benchmark yourself](./docs/benchmark.md).
## Installation
```bash
npm install better-sqlite3
```
> Requires Node.js v14.21.1 or later. Prebuilt binaries are available for [LTS versions](https://nodejs.org/en/about/releases/). If you have trouble installing, check the [troubleshooting guide](./docs/troubleshooting.md).
## Usage
```js
const db = require('better-sqlite3')('foobar.db', options);
const row = db.prepare('SELECT * FROM users WHERE id = ?').get(userId);
console.log(row.firstName, row.lastName, row.email);
```
Though not required, [it is generally important to set the WAL pragma for performance reasons](https://github.com/WiseLibs/better-sqlite3/blob/master/docs/performance.md).
```js
db.pragma('journal_mode = WAL');
```
##### In ES6 module notation:
```js
import Database from 'better-sqlite3';
const db = new Database('foobar.db', options);
db.pragma('journal_mode = WAL');
```
## Why should I use this instead of [node-sqlite3](https://github.com/mapbox/node-sqlite3)?
- `node-sqlite3` uses asynchronous APIs for tasks that are either CPU-bound or serialized. That's not only bad design, but it wastes tons of resources. It also causes [mutex thrashing](https://en.wikipedia.org/wiki/Resource_contention) which has devastating effects on performance.
- `node-sqlite3` exposes low-level (C language) memory management functions. `better-sqlite3` does it the JavaScript way, allowing the garbage collector to worry about memory management.
- `better-sqlite3` is simpler to use, and it provides nice utilities for some operations that are very difficult or impossible in `node-sqlite3`.
- `better-sqlite3` is much faster than `node-sqlite3` in most cases, and just as fast in all other cases.
#### When is this library not appropriate?
In most cases, if you're attempting something that cannot be reasonably accomplished with `better-sqlite3`, it probably cannot be reasonably accomplished with SQLite in general. For example, if you're executing queries that take one second to complete, and you expect to have many concurrent users executing those queries, no amount of asynchronicity will save you from SQLite's serialized nature. Fortunately, SQLite is very *very* fast. With proper indexing, we've been able to achieve upward of 2000 queries per second with 5-way-joins in a 60 GB database, where each query was handling 5–50 kilobytes of real data.
If you have a performance problem, the most likely causes are inefficient queries, improper indexing, or a lack of [WAL mode](./docs/performance.md)—not `better-sqlite3` itself. However, there are some cases where `better-sqlite3` could be inappropriate:
- If you expect a high volume of concurrent reads each returning many megabytes of data (i.e., videos)
- If you expect a high volume of concurrent writes (i.e., a social media site)
- If your database's size is near the terabyte range
For these situations, you should probably use a full-fledged RDBMS such as [PostgreSQL](https://www.postgresql.org/).
## Upgrading
Upgrading your `better-sqlite3` dependency can potentially introduce breaking changes, either in the `better-sqlite3` API (if you upgrade to a new [major version](https://semver.org/)), or between your existing database(s) and the underlying version of SQLite. Before upgrading, review:
* [`better-sqlite3` release notes](https://github.com/WiseLibs/better-sqlite3/releases)
* [SQLite release history](https://www.sqlite.org/changes.html)

node-bindings
=============
### Helper module for loading your native module's `.node` file
This is a helper module for authors of Node.js native addon modules.
It is basically the "swiss army knife" of `require()`ing your native module's
`.node` file.
Throughout the course of Node's native addon history, addons have ended up being
compiled in a variety of different places, depending on which build tool and which
version of node was used. To make matters worse, now the `gyp` build tool can
produce either a __Release__ or __Debug__ build, each being built into different
locations.
This module checks _all_ the possible locations that a native addon would be built
at, and returns the first one that loads successfully.
Installation
------------
Install with `npm`:
``` bash
$ npm install --save bindings
```
Or add it to the `"dependencies"` section of your `package.json` file.
Example
-------
`require()`ing the proper bindings file for the current node version, platform
and architecture is as simple as:
``` js
var bindings = require('bindings')('binding.node')
// Use your bindings defined in your C files
bindings.your_c_function()
```
Nice Error Output
-----------------
When the `.node` file could not be loaded, `node-bindings` throws an Error with
a nice error message telling you exactly what was tried. You can also check the
`err.tries` Array property.
```
Error: Could not load the bindings file. Tried:
→ /Users/nrajlich/ref/build/binding.node
→ /Users/nrajlich/ref/build/Debug/binding.node
→ /Users/nrajlich/ref/build/Release/binding.node

→ /Users/nrajlich/ref/Release/binding.node
→ /Users/nrajlich/ref/build/default/binding.node

at bindings (/Users/nrajlich/ref/node_modules/bindings/bindings.js:84:13)

at Object.Module._extensions..js (module.js:467:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
...
```
The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.

Used by [`got`](https://github.com/sindresorhus/got).
## Install
```
$ npm install decompress-response
```
## Usage
```js
const http = require('http');
const decompressResponse = require('decompress-response');
http.get('https://sindresorhus.com', response => {
response = decompressResponse(response);
});
```
## API
### decompressResponse(response)
Returns the decompressed HTTP response stream.
#### response
Type: [`http.IncomingMessage`](https://nodejs.org/api/http.html#http_class_http_incomingmessage)

Changelog
=========
v0.6.0
------
- Updated "devDependencies" versions to fix vulnerability alerts
- Dropped support of io.js and node.js v0.12.x and lower since new versions of
"devDependencies" couldn't work with those old node.js versions
(minimal supported version of node.js now is v4.0.0)
v0.5.1
------
- Fix prototype pollution vulnerability (thanks to @mwakerman for the PR)
- Avoid using deprecated Buffer API (thanks to @ChALkeR for the PR)
v0.5.0
------
- Auto-testing provided by Travis CI;
- Support older Node.JS versions (`v0.11.x` and `v0.10.x`);
- Removed tests files from npm package.
v0.4.2
------
- Fix for `null` as an argument.
v0.4.1
------
- Removed test code from <b>npm</b> package
([see pull request #21](https://github.com/unclechu/node-deep-extend/pull/21));
- Increased minimal version of Node from `0.4.0` to `0.12.0`
(because can't run tests on lesser version anyway).
v0.4.0
------
- **WARNING!** Broken backward compatibility with `v0.3.x`;
- Fixed bug with extending arrays instead of cloning;
- Deep cloning for arrays;
- Check for own property;
- Fixed some documentation issues;
- Strict JS mode.

# detect-libc
Node.js module to detect details of the C standard library (libc)
implementation provided by a given Linux system.
Currently supports detection of GNU glibc and MUSL libc.
Provides asychronous and synchronous functions for the
family (e.g. `glibc`, `musl`) and version (e.g. `1.23`, `1.2.3`).
The version numbers of libc implementations
are not guaranteed to be semver-compliant.
For previous v1.x releases, please see the
[v1](https://github.com/lovell/detect-libc/tree/v1) branch.
## Install
```sh
npm install detect-libc
```
## API
### GLIBC
```ts
const GLIBC: string = 'glibc';
```
A String constant containing the value `glibc`.
### MUSL
```ts
const MUSL: string = 'musl';
```
A String constant containing the value `musl`.
### family
```ts
function family(): Promise<string | null>;
```
Resolves asychronously with:
* `glibc` or `musl` when the libc family can be determined
* `null` when the libc family cannot be determined
* `null` when run on a non-Linux platform
```js
const { family, GLIBC, MUSL } = require('detect-libc');
switch (await family()) {
case GLIBC: ...
case MUSL: ...
case null: ...
}
```
### familySync
```ts
function familySync(): string | null;
```
Synchronous version of `family()`.
```js
const { familySync, GLIBC, MUSL } = require('detect-libc');
switch (familySync()) {
case GLIBC: ...
case MUSL: ...
case null: ...
}
```
### version
```ts
function version(): Promise<string | null>;
```
Resolves asychronously with:
* The version when it can be determined
* `null` when the libc family cannot be determined
* `null` when run on a non-Linux platform
```js
const { version } = require('detect-libc');
const v = await version();
if (v) {
const [major, minor, patch] = v.split('.');
}
```
### versionSync
```ts
function versionSync(): string | null;
```
Synchronous version of `version()`.
```js
const { versionSync } = require('detect-libc');
const v = versionSync();
if (v) {
const [major, minor, patch] = v.split('.');
}
```
### isNonGlibcLinux
```ts
function isNonGlibcLinux(): Promise<boolean>;
```
Resolves asychronously with:
* `false` when the libc family is `glibc`
* `true` when the libc family is not `glibc`
* `false` when run on a non-Linux platform
```js
const { isNonGlibcLinux } = require('detect-libc');
if (await isNonGlibcLinux()) { ... }
```
### isNonGlibcLinuxSync
```ts
function isNonGlibcLinuxSync(): boolean;
```
Synchronous version of `isNonGlibcLinux()`.
```js
const { isNonGlibcLinuxSync } = require('detect-libc');
if (isNonGlibcLinuxSync()) { ... }
```

# end-of-stream
A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
npm install end-of-stream
[![Build status](https://travis-ci.org/mafintosh/end-of-stream.svg?branch=master)](https://travis-ci.org/mafintosh/end-of-stream)
## Usage
Simply pass a stream and a callback to the `eos`.
Both legacy streams, streams2 and stream3 are supported.
``` js
var eos = require('end-of-stream');
eos(readableStream, function(err) {
// this will be set to the stream instance
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended', this === readableStream);
});
eos(writableStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished', this === writableStream);
});
eos(duplexStream, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended and finished', this === duplexStream);
});
eos(duplexStream, {readable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has finished but might still be readable');
});
eos(duplexStream, {writable:false}, function(err) {
if (err) return console.log('stream had an error or closed early');
console.log('stream has ended but might still be writable');
});
eos(readableStream, {error:false}, function(err) {
// do not treat emit('error', err) as a end-of-stream
});
```

# expand-template
> Expand placeholders in a template string.
[![npm](https://img.shields.io/npm/v/expand-template.svg)](https://www.npmjs.com/package/expand-template)
![Node version](https://img.shields.io/node/v/expand-template.svg)
[![Build Status](https://travis-ci.org/ralphtheninja/expand-template.svg?branch=master)](https://travis-ci.org/ralphtheninja/expand-template)
[![JavaScript Style Guide](https://img.shields.io/badge/code_style-standard-brightgreen.svg)](https://standardjs.com)
## Install
```
$ npm i expand-template -S
```
## Usage
Default functionality expands templates using `{}` as separators for string placeholders.
```js
var expand = require('expand-template')()
var template = '{foo}/{foo}/{bar}/{bar}'
console.log(expand(template, {
foo: 'BAR',
bar: 'FOO'
}))
// -> BAR/BAR/FOO/FOO
```
Custom separators:
```js
var expand = require('expand-template')({ sep: '[]' })
var template = '[foo]/[foo]/[bar]/[bar]'
console.log(expand(template, {
foo: 'BAR',
bar: 'FOO'
}))
// -> BAR/BAR/FOO/FOO
```

### Convert a `file:` URI to a file path
[![Build Status](https://travis-ci.org/TooTallNate/file-uri-to-path.svg?branch=master)](https://travis-ci.org/TooTallNate/file-uri-to-path)
Accepts a `file:` URI and returns a regular file path suitable for use with the
`fs` module functions.
Installation
------------
Install with `npm`:
``` bash
$ npm install file-uri-to-path
```
Example
-------
``` js
var uri2path = require('file-uri-to-path');
uri2path('file://localhost/c|/WINDOWS/clock.avi');
// "c:\\WINDOWS\\clock.avi"
uri2path('file:///c|/WINDOWS/clock.avi');
// "c:\\WINDOWS\\clock.avi"
uri2path('file://localhost/c:/WINDOWS/clock.avi');
// "c:\\WINDOWS\\clock.avi"
uri2path('file://hostname/path/to/the%20file.txt');
// "\\\\hostname\\path\\to\\the file.txt"
uri2path('file:///c:/path/to/the%20file.txt');
// "c:\\path\\to\\the file.txt"
```
