As a loadable extension

If you want to use sqlite-http as a Runtime-loadable extension, Download the http0.dylib (for MacOS), http0.so (Linux), or http0.dll (Windows) file from a release and load it into your SQLite environment.

Note: The 0 in the filename (http0.dylib/ http0.so/http0.dll) denotes the major version of sqlite-http. Currently sqlite-http is pre v1, so expect breaking changes in future versions.

For example, if you are using the SQLite CLI, you can load the library like so:

.load ./http0
select http_version();
-- v0.0.1

Or in Python, using the builtin sqlite3 module:

import sqlite3

con = sqlite3.connect(":memory:")


print(con.execute("select http_version()").fetchone())
# ('v0.0.1',)

Or in Node.js using better-sqlite3:

const Database = require("better-sqlite3");
const db = new Database(":memory:");


console.log(db.prepare("select http_version()").get());
// { 'http_version()': 'v0.0.1' }

Or with Datasette, with the "no network" option to limit DDoS attacks:

datasette data.db --load-extension ./http0-no-net
