# 📦📡 ***importly*** — import map generator

importly is a command-line utility that generates [import maps](https://github.com/WICG/import-maps).

so your apps can load es module packages without a bundler.

works nicely with [es-module-shims](https://github.com/guybedford/es-module-shims).




## 🛸 importly basic usage

```sh

npx importly < package-lock.json > importmap.json

```




**`--host=node_modules`**  

specify where the import map points to.  

where the dependencies will be loaded from.  

- `--host=node_modules` *(default)* — point to your node_modules directory

- `--host=unpkg` — point to the [unpkg](https://unpkg.com/) cdn

- `--host=jsdelivr` — point to the [jsdelivr](https://www.jsdelivr.com/) cdn




**`--dev`**  

include your package's devDependencies.  




**`--lookup=node_modules`**  

tell importly where to seek information about packages.  

it needs to inspect each package json.  

- `--lookup=node_modules` *(default)* — look in your local node_modules directory

- `--lookup=unpkg` — query the [unpkg](https://unpkg.com/) cdn

- `--lookup=jsdelivr` — query the [jsdelivr](https://www.jsdelivr.com/) cdn




**`--root=/`**  

the url prefix that leads to your node_modules directory.  

this affects where the importmap is pointing to.  

only applies when `--host=node_modules`.  

- `--root=/` *(default)* — find node_modules at your server root

- `--root=""` — find node_modules in the current directory

- `--root=/my/special/path/` — find node_modules at `/my/special/path/node_modules`




**`--semver=exact`**  

the semver prefix to use on the import map versions.  

only applies when pointing to a cloud cdn.  

- `--semver=exact` or `--semver=""` *(default)* no prefix, use pinned versions

- `--semver=major` or `--semver=^` pin major version, with caret prefix

- `--semver=minor` or `--semver=~` pin minor version, with tilde prefix




**`--mini`**  

minify importmap output.  

eliminates whitespace.  




## 🌠 the more you know, about importly

you don't have to use a `package-lock.json`

- a `package.json` will work.

- actually, any json that has `dependencies` will work.

- however, the `package-lock.json` is better because it includes subdependencies (and they're scoped, which means your dependencies can use different versions of a single subdependency)

scoped subdependencies only work when

- you're using a `package-lock.json`

- and you're using `--host=node_modules`

works offline when

- you're using `--host=node_modules`

- and you're using `--lookup=node_modules`
