Snowpack-start NPM

snowpack-start

⛔ DEPRECATED ⛔

snowpack-start is no longer developed or maintained (and neither is Snowpack).

Switching to the actively maintained Vite is recommended.

What is Snowpack?
Snowpack is a lightning-fast frontend build tool, designed for the modern web. It is an alternative to heavier, more complex bundlers like webpack or Parcel in your development workflow.

The problem: manually customizing templates from create-snowpack-app was annoying.

The solution: snowpack-start (snowpack-init was already taken). snowpack-start installs packages and generates configuration boilerplate so you can get to developing faster.

Usage

Node version ≥ 10 is required.

$ npx snowpack-start [project-directory] [other-options]

All CLI options (including project directory) are optional.

With no CLI options:

With some CLI options:

Using all CLI options and skipping prompts entirely is also possible.

⚠️ Don't install @snowpack/plugin-run-script or @snowpack/plugin-build-script unless you have a reason to! They're not required to run Snowpack and are for additional processing that isn't already handled by existing plugins.

Passive options do not have prompts.

Syntax	Description

`--no-use-yarn`	Don't use Yarn
`--use-pnpm`	Use pnpm

`--no-skip-git-init`	Don't skip git init

Default Options

On startup, snowpack-start will look for a .snowpackstart.js file in the home directory. If it exists, then the options in that file are loaded as default options. Otherwise, the built-in default options are used.

Passive defaults will always be applied regardless of whether the defaults flag has been passed on the command line. Active defaults will only be applied if -d or --defaults has been passed. If not applied, active defaults will be set as the initial selections/values of their corresponding prompts.

Loading Options From Files

Specify paths to files (extension optional), and options will be loaded from them:

Order Of Operations

Defaults >> Files >> CLI >> Prompts

Later options overwrite earlier ones, with the exception of the other deps options:

The other deps options are instead additive, so later deps will be added to the existing deps. To clear previous deps, use none in files or CLI:

Issues

Known

Jest configs for Snowpack are only available for React, Preact (JS+TS) and Svelte (JS only), and do not yet support Jest 27.
eslint --init only supports React and Vue, additional setup required for Svelte, Preact, and LitElement.
eslint --init only installs packages with npm, no option to use Yarn or pnpm.
Starting with Snowpack v3.1 and as of v3.8.8, image/JSON imports break builds using the built-in bundler (#3109). A workaround is automatically added if snowpack is selected as the bundler.
