libsql-stateless-easy

libsql-stateless-easy

Thin libSQL stateless HTTP driver for TypeScript and JavaScript for the edge but easy 🚀

• ✅ Supported runtime environments: Web API (browser, serverless), Bun, Node.js (>=18)
• ✅ Is extremely light: 8.3kB (unpacked)* / 3.5kB (gzipped)
• ✅ Is built for: Quick stateless query execution. (Mainly for serverless and edge functions.)
• ✅ Supports everything in @libsql/client/web **except interactive transactions.
• ✅ Is Atomic and stateless, every function performs complete execution in exactly 1 roundtrip.
• ✅ libsql-stateless-easy is simply a drop-in replacement and exactly same API as @libsql/client/web.

* The actual js that is included with your project. (Excluding the type definitions and 2 copies of the main js for esm and cjs. (because you're gonna use one of them))
**Interactive transactions are not supported because this lib is stateless but transactions are supported.

Installation

$ npm i libsql-stateless-easy #pnpm, yarn, etc.
# or
$ bun add libsql-stateless-easy

Client Usage

libsql-stateless-easy's client has the exact same API as @libsql/client/web's client.

    import { createClient } from "libsql-stateless-easy";
    //or
    const { createClient } = require("libsql-stateless-easy");

    const client = createClient({
        url: "https://da-fish-mandible.turso.io",
        authToken: "fksdgfgksdgfksdg.javsdKDGKSBkgsdfg289374dg"
    });
    
    const res = await client.batch([
        {
            sql: "select * from contacts where contact_id = ?;",
            args: [3]
        },
        "select first_name, last_name, email from contacts where contact_id = 2",
        {
            sql: "insert into contacts (contact_id,first_name,last_name,email,phone) values (?,?,?,?,?);",
            args: [6,"glomm","feru","[e-mail]","001"]
        },
        {
            sql: "delete from contacts where contact_id = :kkl",
            args: {kkl: 6}
        }
    ]);
    console.log(res);

    const res2 = await client.execute({
        sql: "select first_name, last_name, email, contact_id from contacts where contact_id = ?;",
        args: [1]
    });
    console.log(res2);

    const res3 = await client.execute("select first_name, last_name, email, contact_id from contacts where contact_id = 1;");
    console.log(res3);

Drizzle (and other ORMs)

libsql-stateless-easy's client works with drizzle (and other ORMs) out-of-the-box. This library implements the same Interface is the official client and therefore works with all the ORMs that the official client works with.

    import { createClient } from "libsql-stateless-easy";
    import { drizzle } from 'drizzle-orm/libsql';

    const client = createClient({
        url: "https://da-fish-mandible.turso.io",
        authToken: "fksdgfgksdgfksdg.javsdKDGKSBkgsdfg289374dg"
    });

    const db = drizzle(client);

    const result = await db.select().from(table_name).all();
    console.log(result);

• This library has the same LibsqlError codes as @libsql/client

Performance

This library checks your configs, environments and server compatibility by default.
However this is kinda resource intensive if you're creating client instances often.
So, IF YOU ARE SURE YOUR CONFIGURATION, ENVIRONMENT AND SERVER VERSION ARE CORRECT, PLEASE DISABLE THE CHECKS FOR EVEN BETTER PERFORMANCE.

    const client = createClient({
        url: "https://da-fish-mandible.turso.io",
        authToken: "fksdgfgksdgfksdg.javsdKDGKSBkgsdfg289374dg",
        disableCriticalChecks: true
    });

Custom Fetch

Pass your own implementation of fetch or fetch-like function if you don't want libsql-stateless-easy to use the global fetch or if your global fetch does not exist.

    import { createClient, libsqlFetchLike } from 'libsql-stateless-easy';

    const client = createClient({
        url: "https://da-fish-mandible.turso.io",
        authToken: "fksdgfgksdgfksdg.javsdKDGKSBkgsdfg289374dg",
        fetch: async (...args: Parameters<libsqlFetchLike>): ReturnType<libsqlFetchLike> => {
                //implement your own fetch here (look at examples/custom_fetch/libsql_isomorphic_fetch.ts for concrete example)
                /** NOTE:
                 * args[0] is the url string
                 * args[1] is the request init
                 */
            );
        }
    });

    const res = await client.execute("select * from contacts;");
    console.log(res);

Modularity

libsql-stateless-easy is extremely modular. execute, batch, etc. can be used without initiating a client.

    import { libsqlBatchTransaction, libsqlExecute } from "libsql-stateless-easy";
    //or
    const { libsqlBatchTransaction, libsqlExecute } = require("libsql-stateless-easy");

    const config = {
        url: "https://da-fish-mandible.turso.io",
        authToken: "fksdgfgksdgfksdg.javsdKDGKSBkgsdfg289374dg"
    };
    
    const res = await libsqlBatchTransaction(
        config,
        [
            {
                sql: "select * from contacts where contact_id = ?;",
                args: [3]
            },
            "select first_name, last_name, email from contacts where contact_id = 2",
            {
                sql: "insert into contacts (contact_id,first_name,last_name,email,phone) values (?,?,?,?,?);",
                args: [6,"glomm","feru","[e-mail]","001"]
            },
            {
                sql: "delete from contacts where contact_id = :kkl",
                args: {kkl: 6}
            }
        ]
    );
    console.log(res);

    const res2 = await libsqlExecute(
        config,
        {
            sql: "select first_name, last_name, email, contact_id from contacts where contact_id = ?;",
            args: [1]
        }
    );
    console.log(res2);

    const res3 = await libsqlExecute(config, "select first_name, last_name, email, contact_id from contacts where contact_id = 1;", []);
    console.log(res3);

libsql-stateless-easy's client just conveniently packages these individually executable functions to conform to the official sdk interface.

List of other stuff in this library

Feel free to explore them (however you don't need to as they've been neatly packaged into the client)

    import {
        libsqlValueBuilder, libsqlArgumentsBuilder, libsqlStatementBuilder, libsqlBatchReqStepsBuilder, libsqlBatchReqStepExecCondBuilder, libsqlTransactionBeginStatement,
        libsqlValueParser, libsqlStatementResParser, libsqlBatchStreamResParser, libsqlTransactionBatchStreamResParser,
        libsqlExecute, //has easier API than `libsql-stateless`'s function of the same name
        libsqlBatch, //has easier API than `libsql-stateless`'s function of the same name
        libsqlServerCompatCheck, //has easier API than `libsql-stateless`'s function of the same name,
        libsqlBatchTransaction, libsqlExecuteMultiple
        createClient //used above
    } from "libsql-stateless-easy";
