Check the [Node-API version matrix](https://nodejs.org/api/n-api.html#node-api-version-matrix) to ensure your Node version supports one of these. The prebuilt binaries should be supported on Node v10+. + +The module uses [`prebuild-install`](https://github.com/prebuild/prebuild-install) to download the prebuilt binary for your platform, if it exists. These binaries are hosted on GitHub Releases for `sqlite3` versions above 5.0.2, and they are hosted on S3 otherwise. The following targets are currently provided: + +* `darwin-arm64` +* `darwin-x64` +* `linux-arm64` +* `linux-x64` +* `linuxmusl-arm64` +* `linuxmusl-x64` +* `win32-ia32` +* `win32-x64` + +Unfortunately, [prebuild](https://github.com/prebuild/prebuild/issues/174) cannot differentiate between `armv6` and `armv7`, and instead uses `arm` as the `{arch}`. Until that is fixed, you will still need to install `sqlite3` from [source](#source-install). + +Support for other platforms and architectures may be added in the future if CI supports building on them. + +If your environment isn't supported, it'll use `node-gyp` to build SQLite, but you will need to install a C++ compiler and linker. + +### Other ways to install + +It is also possible to make your own build of `sqlite3` from its source instead of its npm package ([See below.](#source-install)). + +The `sqlite3` module also works with [node-webkit](https://github.com/rogerwang/node-webkit) if node-webkit contains a supported version of Node.js engine. [(See below.)](#building-for-node-webkit) + +SQLite's [SQLCipher extension](https://github.com/sqlcipher/sqlcipher) is also supported. [(See below.)](#building-for-sqlcipher) + +# API + +See the [API documentation](https://github.com/TryGhost/node-sqlite3/wiki/API) in the wiki. + +# Usage + +**Note:** the module must be [installed](#installing) before use. + +``` js +const sqlite3 = require('sqlite3').verbose(); +const db = new sqlite3.Database(':memory:'); + +db.serialize(() => { + db.run("CREATE TABLE lorem (info TEXT)"); + + const stmt = db.prepare("INSERT INTO lorem VALUES (?)"); + for (let i = 0; i < 10; i++) { + stmt.run("Ipsum " + i); + } + stmt.finalize(); + + db.each("SELECT rowid AS id, info FROM lorem", (err, row) => { + console.log(row.id + ": " + row.info); + }); +}); + +db.close(); +``` + +## Source install + +To skip searching for pre-compiled binaries, and force a build from source, use + +```bash +npm install --build-from-source +``` + +The sqlite3 module depends only on libsqlite3. However, by default, an internal/bundled copy of sqlite will be built and statically linked, so an externally installed sqlite3 is not required. + +If you wish to install against an external sqlite then you need to pass the `--sqlite` argument to `npm` wrapper: + +```bash +npm install --build-from-source --sqlite=/usr/local +``` + +If building against an external sqlite3 make sure to have the development headers available. Mac OS X ships with these by default. If you don't have them installed, install the `-dev` package with your package manager, e.g. `apt-get install libsqlite3-dev` for Debian/Ubuntu. Make sure that you have at least `libsqlite3` >= 3.6. + +Note, if building against homebrew-installed sqlite on OS X you can do: + +```bash +npm install --build-from-source --sqlite=/usr/local/opt/sqlite/ +``` + +## Custom file header (magic) + +The default sqlite file header is "SQLite format 3". You can specify a different magic, though this will make standard tools and libraries unable to work with your files. + +```bash +npm install --build-from-source --sqlite_magic="MyCustomMagic15" +``` + +Note that the magic *must* be exactly 15 characters long (16 bytes including null terminator). + +## Building for node-webkit + +Because of ABI differences, `sqlite3` must be built in a custom to be used with [node-webkit](https://github.com/rogerwang/node-webkit). + +To build `sqlite3` for node-webkit: + +1. Install [`nw-gyp`](https://github.com/rogerwang/nw-gyp) globally: `npm install nw-gyp -g` *(unless already installed)* + +2. Build the module with the custom flags of `--runtime`, `--target_arch`, and `--target`: + +```bash +NODE_WEBKIT_VERSION="0.8.6" # see latest version at https://github.com/rogerwang/node-webkit#downloads +npm install sqlite3 --build-from-source --runtime=node-webkit --target_arch=ia32 --target=$(NODE_WEBKIT_VERSION) +``` + +You can also run this command from within a `sqlite3` checkout: + +```bash +npm install --build-from-source --runtime=node-webkit --target_arch=ia32 --target=$(NODE_WEBKIT_VERSION) +``` + +Remember the following: + +* You must provide the right `--target_arch` flag. `ia32` is needed to target 32bit node-webkit builds, while `x64` will target 64bit node-webkit builds (if available for your platform). + +* After the `sqlite3` package is built for node-webkit it cannot run in the vanilla Node.js (and vice versa). + * For example, `npm test` of the node-webkit's package would fail. + +Visit the “[Using Node modules](https://github.com/rogerwang/node-webkit/wiki/Using-Node-modules)” article in the node-webkit's wiki for more details. + +## Building for SQLCipher + +For instructions on building SQLCipher, see [Building SQLCipher for Node.js](https://coolaj86.com/articles/building-sqlcipher-for-node-js-on-raspberry-pi-2/). Alternatively, you can install it with your local package manager. + +To run against SQLCipher, you need to compile `sqlite3` from source by passing build options like: + +```bash +npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=/usr/ + +node -e 'require("sqlite3")' +``` + +If your SQLCipher is installed in a custom location (if you compiled and installed it yourself), you'll need to set some environment variables: + +### On OS X with Homebrew + +Set the location where `brew` installed it: + +```bash +export LDFLAGS="-L`brew --prefix`/opt/sqlcipher/lib" +export CPPFLAGS="-I`brew --prefix`/opt/sqlcipher/include/sqlcipher" +npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=`brew --prefix` + +node -e 'require("sqlite3")' +``` + +### On most Linuxes (including Raspberry Pi) + +Set the location where `make` installed it: + +```bash +export LDFLAGS="-L/usr/local/lib" +export CPPFLAGS="-I/usr/local/include -I/usr/local/include/sqlcipher" +export CXXFLAGS="$CPPFLAGS" +npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=/usr/local --verbose + +node -e 'require("sqlite3")' +``` + +### Custom builds and Electron + +Running `sqlite3` through [electron-rebuild](https://github.com/electron/electron-rebuild) does not preserve the SQLCipher extension, so some additional flags are needed to make this build Electron compatible. Your `npm install sqlite3 --build-from-source` command needs these additional flags (be sure to replace the target version with the current Electron version you are working with): + +```bash +--runtime=electron --target=18.2.1 --dist-url=https://electronjs.org/headers +``` + +In the case of MacOS with Homebrew, the command should look like the following: + +```bash +npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=`brew --prefix` --runtime=electron --target=18.2.1 --dist-url=https://electronjs.org/headers +``` + +# Testing + +```bash +npm test +``` + +# Contributors + +* [Daniel Lockyer](https://github.com/daniellockyer) +* [Konstantin Käfer](https://github.com/kkaefer) +* [Dane Springmeyer](https://github.com/springmeyer) +* [Will White](https://github.com/willwhite) +* [Orlando Vazquez](https://github.com/orlandov) +* [Artem Kustikov](https://github.com/artiz) +* [Eric Fredricksen](https://github.com/grumdrig) +* [John Wright](https://github.com/mrjjwright) +* [Ryan Dahl](https://github.com/ry) +* [Tom MacWright](https://github.com/tmcw) +* [Carter Thaxton](https://github.com/carter-thaxton) +* [Audrius Kažukauskas](https://github.com/audriusk) +* [Johannes Schauer](https://github.com/pyneo) +* [Mithgol](https://github.com/Mithgol) +* [Kewde](https://github.com/kewde) + +# Acknowledgments + +Thanks to [Orlando Vazquez](https://github.com/orlandov), +[Eric Fredricksen](https://github.com/grumdrig) and +[Ryan Dahl](https://github.com/ry) for their SQLite bindings for node, and to mraleph on Freenode's #v8 for answering questions. + +This module was originally created by [Mapbox](https://mapbox.com/) & is now maintained by [Ghost](https://ghost.org). + +# Changelog + +We use [GitHub releases](https://github.com/TryGhost/node-sqlite3/releases) for notes on the latest versions.
