Installation

Get started with AbsoluteJS in minutes using the CLI or manual setup.

#Prerequisites

AbsoluteJS requires Bun version 1.2 or higher. If you don't have Bun installed, run:

BASH

curl -fsSL https://bun.sh/install | bash

To keep several Bun versions side by side, pin one per project, or use AbsoluteJS's patched builds, install Bun with bvm instead.

The fastest way to start a new AbsoluteJS project is with the create-absolutejs CLI:

BASH

bun create absolutejs my-app

You can also specify options directly:

BASH

bun create absolutejs my-app --react --db postgresql --orm drizzle

Available options include:

--reactAdd React; --svelte, --vue, --angular, --html and --htmx add the others (combine several)

--dbpostgresql, mysql, mariadb, sqlite, singlestore, cockroachdb, mssql, mongodb, gel, none

--ormdrizzle (every engine except mongodb and gel), prisma (every engine except singlestore and gel), none

--db-hostneon (postgresql), planetscale (postgresql or mysql), turso (sqlite)

--authabs to include @absolutejs/auth setup, or none

A new AbsoluteJS project has this structure:

my-app/

build/Build output and compiled assets

db/DB and ORM related stuff

src/

backend/

handlers/Request handlers

plugins/Elysia plugins

assets/Static assets

server.tsElysia server entry point

frontend/

pages/Page components

components/Shared components

styles/CSS and styling files

types/TypeScript type definitions

absolute.config.tsAbsoluteJS build configuration

package.json

tsconfig.json

.env

To add AbsoluteJS to an existing project:

BASH

bun add @absolutejs/absolute elysia
