Design Hub developer guide - company support plugins

Design Hub's company supports plugins are a collection of API endpoints that facilitate integrating the application into an organization's project management, authorization and enterprise resource planning systems. As such it handles concepts other than the rest of the plugin types. The mechanism of handling their functionality reuses the overall plugin system however, so there are 2 technical approaches to defining and loading plugins:

NodeJS modules, stored in a folder set by Design Hub's configuration file (servicesDirectory)
REST API implementing microservices, loaded through URLs defined in Design Hub's configuration file (remoteServices)

As described below in the specification, the 2 approaches follow the same concepts, and internally are managed by the same service, so outgoing call arguments are the same regardless of the technical choice, and your plugin's configuration will have identical behaviour in the application regardless of the API.

NodeJS module API

Company support plugins are NodeJS modules, denoted by their filename: *.company.js and location in the services directory as configured during installation.

A company support plugin exports the following properties:

Name	Type	Required	Description
`name`	string	yes	Unique identifier of the plugin, used by Design Hub for identification and internal communication. If multiple plugins use the same identifier, the last one to be loaded overrides the others.
`label`	string	yes	Human readable name of the plugin, used by Design Hub to display GUI elements related to this plugin.
`getProjects`	async function	no	Called automatically during initialization and then on a preconfigured daily schedule to obtain an overall list of projects to be used by the application. Arguments: none Return value: `Promise` of array of objects. Each object corresponds to a project. The objects in the array should contain `name` and `label` attributes for a project. Label will be used on the GUI.
`getUserProjects`	async function	no	Called automatically during the successful authentication of a user, to obtain project assignments. The function must return a Promise of the results. The results are stored in the application database and used for authorization. Arguments: `user (object)` A javascript object describing the calling user `this` includes `domain` for the current call Return value: `Promise` of array of objects. Each object corresponds to a project. The objects in the array should contain `name` and `label` attributes for a project.
`getUserGroups`	async function	no	Called automatically during the successful authentication of a user, to obtain group memberships. The function must return a Promise of the results. The results are stored in the application database and used for authorization. Arguments: `user (object)` A javascript object describing the calling user `this` includes `domain` for the current call Return value: `Promise` of array of string. Each string corresponds to a group's name.
`checkCompound`	async function	no	Called when a user attempts to share a compound. This function may return drawing quality issues regarding the 2D structure of the compound. Arguments: `structure (string)` An MRV formatted chemical structure `this` includes `domain` for the current call Return value: `Promise` of an object. The object must include an array of strings under the `issues` key. Each string corresponds to one drawing quality issue, e.g.: `Unspecified stereo centers`.
`getID`	async function	no	Called when a user attempts to share a compound, and then periodically depending on configuration, until a substance ID is found for the compound. This function may return a single identifier for a compound from a small molecule registration system. Arguments: `structure (string)` MRV formatted chemical structure `this` includes `domain` Return value: `Promise` of an optional string. The string must contain the substance ID for the chemical structure. Empty string (or null, undefined) are treated as successful queries without a hit.
`domains`	array of strings	yes	List of domains where this plugin may be used, when authentication is enabled in Design Hub. Use `*` to allow any domain.

Note: you may use _development authentication type to test aspects of your plugin specific to a domain. This authentication type accepts any username, password combination, where the 2 field string match.
