Is it possible to use github to host a web application that supports sqlite database?

Github supports static webpages. Sqlite database is a binary file. Can a static webpage with javascript access make queries on the sqlite database in the same folder?

Many web development projects require a database. This is for demonstration purposes only and does not need to support many users.

Yes, but read-only. sql.js is a Javascript SQLite library which compiles the SQLite C library into Webassembly.

Here's an example of loading an existing SQLite database from a URL and querying it.

Using Fetch API:

// Example DB: https://github.com/lerocha/chinook-database/raw/master/ChinookDatabase/DataSources/Chinook_Sqlite.sqlite
const response = await fetch("/path/to/database.sqlite")
const arrayBuffer = await response.arrayBuffer();
const SQL = await initSqlJs();
const db = new SQL.Database(new Uint8Array(arrayBuffer));
const contents = db.exec("SELECT * FROM my_table");
// contents is now [{columns:['col1','col2',...], values:[[first row], [second row], ...]}]

Using XMLHttpRequest:

const xhr = new XMLHttpRequest();
// For example: https://github.com/lerocha/chinook-database/raw/master/ChinookDatabase/DataSources/Chinook_Sqlite.sqlite
xhr.open('GET', '/path/to/database.sqlite', true);
xhr.responseType = 'arraybuffer';

xhr.onload = e => {
  const uInt8Array = new Uint8Array(this.response);
  const db = new SQL.Database(uInt8Array);
  const contents = db.exec("SELECT * FROM my_table");
  // contents is now [{columns:['col1','col2',...], values:[[first row], [second row], ...]}]
};
xhr.send();
