# Atom.io package and update API
This guide describes the web API used by [apm](https://github.com/atom/apm) and
Atom. The vast majority of use cases are met by the `apm` command-line tool,
which does other useful things like incrementing your version in `package.json`
and making sure you have pushed your git tag. In fact, Atom itself shells out to
`apm` rather than hitting the API directly. If you're curious about how Atom
uses `apm`, see the [PackageManager class](https://github.com/atom/settings-view/blob/master/lib/package-manager.coffee)
in the `settings-view` package.
*This API should be considered pre-release and is subject to change (though significant breaking changes are unlikely).*
### Authorization
For calls to the API that require authentication, provide a valid token from your
[Atom.io account page](https://atom.io/account) in the `Authorization` header.
### Media type
All requests that take parameters require `application/json`.
# API Resources
## Packages
### Listing packages
#### GET /api/packages
Parameters:
- **page** (optional)
- **sort** (optional) - One of `downloads`, `created_at`, `updated_at`, `stars`. Defaults to `downloads`
- **direction** (optional) - `asc` or `desc`. Defaults to `desc`. `stars` can only be ordered `desc`
Returns a list of all packages in the following format:
```json
[
{
"releases": {
"latest": "0.6.0"
},
"name": "thedaniel-test-package",
"repository": {
"type": "git",
"url": "https://github.com/thedaniel/test-package"
}
},
...
]
```
Results are paginated 30 at a time, and links to the next and last pages are
provided in the `Link` header:
```
Link: <https://www.atom.io/api/packages?page=1>; rel="self",
<https://www.atom.io/api/packages?page=41>; rel="last",
<https://www.atom.io/api/packages?page=2>; rel="next"
```
By default, results are sorted by download count, descending.
### Searching packages
#### GET /api/packages/search
Parameters:
- **q** (required) - Search query
- **page** (optional)
- **sort** (optional) - One of `downloads`, `created_at`, `updated_at`, `stars`. Defaults to the relevance of the search query.
- **direction** (optional) - `asc` or `desc`. Defaults to `desc`.
Returns results in the same format as [listing packages](#listing-packages).
### Showing package details
#### GET /api/packages/:package_name
Returns package details and versions for a single package
Parameters:
- **engine** (optional) - Only show packages with versions compatible with this
Atom version. Must be valid [SemVer](http://semver.org).
Returns:
```json
{
"releases": {
"latest": "0.6.0"
},
"name": "thedaniel-test-package",
"repository": {
"type": "git",
"url": "https://github.com/thedaniel/test-package"
},
"versions": [
(see single version output below)
...,
]
}
```
### Creating a package
#### POST /api/packages
Create a new package; requires authentication.
The name and version will be fetched from the `package.json`
file in the specified repository. The authenticating user *must* have access
to the indicated repository.
Parameters:
- **repository** - String. The repository containing the plugin, in the form "owner/repo"
Returns:
- **201** - Successfully created, returns created package.
- **400** - Repository is inaccessible, nonexistent, not an atom package. Possible
error messages include:
- That repo does not exist, isn't an atom package, or atombot does not have access
- The package.json at owner/repo isn't valid
- **409** - A package by that name already exists
### Deleting a package
#### DELETE /api/packages/:package_name
Delete a package; requires authentication.
Returns:
- **204** - Success
- **400** - Repository is inaccessible
- **401** - Unauthorized
### Renaming a package
Packages are renamed by publishing a new version with the name changed in `package.json`
See [Creating a new package version](#creating-a-new-package-version) for details.
Requests made to the previous name will forward to the new name.
### Package Versions
#### GET /api/packages/:package_name/versions/:version_name
Returns `package.json` with `dist` key added for e.g. tarball download:
```json
{
"bugs": {
"url": "https://github.com/thedaniel/test-package/issues"
},
"dependencies": {
"async": "~0.2.6",
"pegjs": "~0.7.0",
"season": "~0.13.0"
},
"description": "Expand snippets matching the current prefix with `tab`.",
"dist": {
"tarball": "https://codeload.github.com/..."
},
"engines": {
"atom": "*"
},
"main": "./lib/snippets",
"name": "thedaniel-test-package",
"publishConfig": {
"registry": "https://...",
},
"repository": {
"type": "git",
"url": "https://github.com/thedaniel/test-package.git"
},
"version": "0.6.0"
}
```
### Creating a new package version
#### POST /api/packages/:package_name/versions
Creates a new package version from a git tag; requires authentication. If `rename`
is not `true`, the `name` field in `package.json` *must* match the current package
name.
#### Parameters
- **tag** - A git tag for the version you'd like to create. It's important to note
that the version name will not be taken from the tag, but from the `version`
key in the `package.json` file at that ref. The authenticating user *must* have
access to the package repository.
- **rename** - Boolean indicating whether this version contains a new name for the package.
#### Returns
- **201** - Successfully created. Returns created version.
- **400** - Git tag not found / Repository inaccessible / package.json invalid
- **409** - Version exists
### Deleting a version
#### DELETE /api/packages/:package_name/versions/:version_name
Deletes a package version; requires authentication.
Note that a version cannot be republished with a different tag if it is deleted.
If you need to delete the latest version of a package for e.g. security reasons,
you'll need to increment the version when republishing.
Returns 204 No Content
