jspm Registry
|
|
---
|
|
|
|
[View the registry file here](https://github.com/jspm/registry/blob/master/registry.json)
|
|
|
|
Pull requests welcome for `registry.json` to add or modify entries.
|
|
|
|
All registry entries are managed here through Github, moderated by the registry maintainers.

Registry
|
|
---
|
|
|
|
Modules are served from _endpoint servers_. Endpoints include `github:` and `npm:`.
|
|
|
|
When requesting a module such as `github:twbs/bootstrap@3.0/js/bootstrap.js`, this corresponds to the URL
|
|
`https://github.jspm.io/twbs/bootstrap@3.0/js/bootstrap.js` and the **GitHub endpoint**, returns the associated code.
|
|
|
|
The registry simply remembers the `github:twbs/bootstrap` part, allowing the shortcut form:
|
|
|
|
```javascript
|
|
System.import('bootstrap@3.0/js/bootstrap');
|
|
```
|
|
|
|
The `registry.json` is just a collection of these mappings:
|
|
|
|
```javascript
|
|
"bootstrap": "github:twbs/bootstrap"
|
|
```
|
|
|
|
Anyone is welcome to submit a mapping.
|
|
|
|
The current supported endpoint servers are:
|
|
|
|
* Github (SPDY optimized)
|
|
* npm (SPDY optimized)
|
|

Package.json Overrides
|
|
---
|
|
|
|
The registry also provides a service for overriding the `package.json` of existing repos.
|
|
|
|
This is useful for enabling jspm functionality in the `package.json` when direct access to the underlying repo is not possible.
|
|
|
|
This is because jspm uses the `package.json` for modular package configuration, including:
|
|
|
|
* Setting the main entry point (`main`)
|
|
* Shim config for globals (`shim`)
|
|
* Map configuration (`map`)
|
|
* Module format (`format`)
|
|
* Auto-enabling minification (`buildOptions.minify`)
|
|
|
|
In this way, the right package options can make any package play well with jspm, without needing any manual configuration at all.
|
|
|
|
Submitting a pull request to the original repo is still preferable to package overrides, this is a convenience service only and not a long term solution.
|
|
|
|
Read more about [configuring packages for jspm](https://github.com/jspm/registry/wiki/Configuring-Packages-for-jspm) in the wiki.
|
|
|
|
Some examples of package.json overrides for common packages:
|
|
* [Bootstrap](https://github.com/jspm/registry/blob/master/package-overrides/github/twbs/bootstrap%403.0.2.json)
|
|
* [Backbone Marionette](https://github.com/jspm/registry/blob/master/package-overrides/github/marionettejs/backbone.marionette%401.2.2.json)
|
|
|
|
Further examples of jspm package.json files for common packages can be found in the [package overrides](https://github.com/jspm/registry/tree/master/package-overrides) section of the registry. Pull requests are encouraged.
|
|
|
|
### Testing Package Overrides
|
|
|
|
Package overrides may take some testing to get exactly the right configuration. The [jspm CLI](https://github.com/jspm/jspm-cli) provides an option to specify the package override for testing in this way.
|
|
|
|
Simply add the `-o` option to an install to set the package override:
|
|
|
|
```
|
|
jspm install github:twbs/bootstrap -o "{ main: 'js/bootstrap', shim: { 'js/bootstrap': ['jquery'] } }"
|
|
```
|
|
|
|
Once tested the exact override can then be included in the here with a pull request.
|
|
|
|
### Submitting a Package Override
|
|
|
|
To submit a new package override:
|
|
|
|
* Fork this repo, then create the file `package_overrides/[endpoint name]/[repo name]@x.y.z.json.
|
|
* Provide the correct configuration according to the configuration guide above.
|
|
* Submit a pull request.
|
|
* If the configuration is correct, this will be accepted and that will instantly enable the functionality on the endpoint.
|
|
|
|
The overrides only apply to exact version, tag or branch names.
