🥇Features

• Aligned to SQLite 3.41.2;

• A single executable file (written in Go);

• HTTP/JSON access, with client libraries for convenience;

• Directly call ws4sqlite on a database (as above), many options available using a YAML companion file;

• In-memory DBs are supported;

• Serving of multiple databases in the same server instance;

• Batching of multiple value sets for a single statement;

• All queries of a call are executed in a transaction;

• For each query/statement, specify if a failure should rollback the whole transaction, or the failure is limited to that query;

• "Stored Statements": define SQL in the server, and call it from the client;

• CORS mode, configurable per-db;

• Scheduled tasks (VACUUM, sql or backups), also configurable per-db;

• Builtin encryption of fields, given a symmetric key;

• Provide initialization statements to execute when a DB is created;

• WAL mode enabled by default, can be disabled;

• Embedded web server to directly serve web pages that can access ws4sqlite without CORS;

• Quite fast!

• Compact codebase;

• Comprehensive test suite (make test);

• 10 os's/arch's directly supported;

• Docker images, for amd64, arm and arm64.

Security Features

• Authentication can be configured

  • on the client, either using HTTP Basic Authentication or specifying the credentials in the request;

  • on the server, either by specifying credentials (also with hashed passwords) or providing a query to look them up in the db itself;

• A database can be opened in read-only mode (only queries will be allowed);

• It's possible to enforce using only stored statements, to avoid some forms of SQL injection and receiving SQL from the client altogether;

• CORS Allowed Origin can be configured and enforced;

• It's possible to bind to a network interface, to limit access.

Some design choices:

• Very thin layer over SQLite. Errors and type translation, for example, are those provided by the SQLite driver;

• Doesn't include HTTPS, as this can be done easily (and much more securely) with a reverse proxy;

• Doesn't support SQLite extensions, to improve portability.
