saso

library5.0.2jsnpmunverified

Zero-configuration bundler for building modern JavaScript/TypeScript applications, currently at v5.0.2. It provides a fast, opinionated build process without configuration files, supporting both CommonJS and ESM outputs. Key differentiators include an intuitive CLI, built-in support for JSX, TypeScript, and CSS modules, and a plugin system for extensibility. Minimal setup required — ideal for quick prototypes or small-to-medium projects. Released under ISC license.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import saso from 'saso'

✗ const saso = require('saso')

ESM-only since v5, default export provides build function.

build

✓ import { build } from 'saso'

✗ const { build } = require('saso')

Named export for programmatic build.

SasoConfig

✓ import { SasoConfig } from 'saso'

✗ import SasoConfig from 'saso'

TypeScript type export, available as type only.

Programmatic build using Saso's default export with entry, output, format, and minification options.

import saso from 'saso'; saso({ entry: './src/index.tsx', outfile: './dist/bundle.js', format: 'esm', minify: true, }).then(() => console.log('Build complete')).catch(console.error);

Debug

Known issues

breakingsaso v5 migrated to ESM-only. CommonJS require() will throw ERR_REQUIRE_ESM.

fix

Use import syntax or upgrade to ESM project.

affects: >=5.0.0

breakingDefault export changed from object to function in v4.

fix

Update to new API: saso(options) instead of new saso.Saso().

affects: >=4.0.0 <5.0.0

deprecatedsaso v3 API using 'new Saso()' is removed.

fix

Migrate to functional API saso(options).

affects: >=4.0.0

gotchaConfiguration file saso.config.js is ignored if programmatic API is used.

fix

Either use CLI or programmatic API exclusively.

affects: >=4.0.0

Errors

Common errors & fixes

TypeError: saso is not a function

Using default import after v5 which exports a function, but bundler may confuse with object.

fix

Ensure you import default as: import saso from 'saso' (not as object destructuring).

Cannot find module 'saso' when using require()

v5 is ESM-only, require() is not supported.

fix

Use import syntax or set type:"module" in package.json.

Error: Unknown option `entry` in SasoConfig

Using old v3 configuration shape with v5.

fix

Update config keys: use 'entry' as string, 'outfile' instead of 'output'.
