Launch

Development

Server: npm run dev:server
Client (webpack dev server): npm run dev:client

This project uses a monorepo setup. In order to contribute to packages following commands should be executed:

Run npm run packages:setup - initial setup, dependency installation, package linking, etc. This command should be executed only a single time.
Run npm run packages:build - build all packages. Run this command after altering the package's code.
Run npm run packages:build --package=<package-name> to build only specified package. For example: npm run packages:build --package=core-components.

Production

Bundle client by issuing npm run build
npm run start

Content repository structure

Repository structure can be altered using tailor configuration file, which must be placed inside the root directory and named tailor.config.js.

Use the tailor.config.js.example file as a template:

$ cp tailor.config.js.example tailor.config.js

and enter the configuration details. At the current time, it is not possible to override the filename or location of the configuration file.

Content repository structures are defined using the following properties:

`SCHEMAS`

An array of Schema objects.

Schema

id String - Schema identifier.

type String - Const for marking activity type.
rootLevel Boolean - Used to define first level (root) activity types
subLevels Array<String> - An array of sub-types.
label String - Display label.

contentContainers Array<String> - Array of content container types that define which content containers can be added.
hasExams Boolean - Activity allows adding exam activities to it.
exams Object - Configuration for activity exams.
relationships Array<ActivityRelationship> - Defines what relationships this activity has to other activities.
meta Array<Metadata> - An array of objects defining activity metadata.

ActivityRelationship

Defines the structure of the activity relationship field.

type String - Defines the name of the relationship. The relationship will be published under this value.
label String - Display label.
placeholder String - Display label for the select picker.
multiple Boolean - Defines if the relationship can have multiple associations chosen. True by default.
searchable Boolean - Defines if the list of activities can be searched. True by default.
allowEmpty Boolean - Defines if the member list can be empty. True by default.
allowCircularLinks Boolean - Defines if a member of the relationship instance can set the owner of that instance as a member of its own instance of that relationship. Example, activity X sets activity Y as its prerequisite. If allowCircualLinks is set to true then activity Y can set activity X as its prerequisite. False by default.
allowInsideLineage Boolean - Defines if an ancestor or a descendant can be a member of the relationship. False by default.
allowedTypes Array<String> - Defines activity types that can be associated in a relationship.

Metadata

Defines the structure of the activity metadata field.

key String - Unique key for the field.
type String - Type of the input component used on the client.
label String - Display label.
placeholder String - Input component placeholder.
validate MetadataValidator - Validator object.
defaultValue * - Default field value.

MetadataValidator

Defines validation rules on an activity metadata field.

rules Object - Contains the following properties:
max Number - Maximum character count.
required Boolean - Defines if the field is required.

`CONTENT_CONTAINERS`

An array of ContentContainer objects.

ContentContainer

Configuration for content containers. Contains the following properties:

type String - const-cased string for marking ContentContainer type.
templateId String - const-cased string that defines which custom ContentContainer is used to display this container. Needs to match the templateId property of the desired custom ContentContainer. If not specified the default ContentContainer is used to display this container.
label String - String used for referencing ContentContainer on the UI.
multiple Boolean - Defines if there can be multiple instances of the ContentContainer inside a single Activity. False by default.
types Array<String> - An array of possible content element types that can exist inside a ContentContainer. If not specified all types of elements are allowed.
displayHeading Boolean - Defines if a heading is displayed on top of the ContentContainer. False by default.
layout Boolean - Defines if elements inside a ContentContainer instance can be placed two in a row. True by default.
config Object - Defines ContentContainer specific properties.
required Boolean - Defines if an instance of the ContentContainer is created if non exist. True by default.
publishedAs String - Defines the name of the file under which the container will be published. Defaults to container. The name of the structure component used is the kebab-cased version of the type property. (example: ABC_DEF -> abc-def)

ElementMetaConfig

Defines the structure of an content element metadata.

type String - Type of content element (example: "IMAGE", "HTML").
inputs Array<ElementMeta> - Defines what meta fields content element has.
relationships Array<ElementRelationship> - Defines what relationship metadata content element has (relationships with content elements from the same or other activities in the repository).

ElementRelationship

Defines the structure of an content element relationship field.

key String - Defines the name of the relationship. The relationship will be published under this value.

  }, {
    "label": "Second",
    "value": "second"
  }]

`PREVIEW_URL`

A string template that will be interpolated on the client using two route params, repositoryId and activityId, into a preview URL for each activity. Example: https://my.url.com/#/repository/{repositoryId}/activity/{activityId}/preview

Workflows

For each schema, workflow can be defined to enable users to track and assign activities which are flagged for tracking. Each workflow is defined by a set of statuses that the activity can have. Workflows are assigned to schemas through schema's workflowId option in tailor configuration file.

Workflows are configured with the following options in the tailor configuration file:

`WORKFLOWS`

An array of Workflow objects.

Workflow

Defines activity statuses for repository workflow. Workflow can be reused across multiple schemas by assigning the same workflow ID to schema's workflowId option.

id String - Workflow identifier.
statuses Array<ActivityStatus> - An array of possible activity statuses.
dueDateWarningThreshold Object - Defines threshold (in days, weeks or months) relative to activity's due date, after which the warning of upcoming due date is displayed.

ActivityStatus

id String - Activity status identifier.
label String - Display label.
color String - Display color.
default Boolean - Defines that the status is the default, which the activity has when it's created.

EXTENSIONS

Tailor supports creation of custom content elements and custom containers. These extensions can have unique content and structure that the default content elements and containers do not support. The template for creating custom content elements can be found here while the template for creating custom containers can be found here.

Installing extensions

copy (or git clone) extension files in extensions/content-<elements or containers>/<my-extension-name>
create index.js file in extensions/content-<elements or containers> directory
in the file from the previous step add

module.exports = ['my-extension-name'];

Note that module.exports is an array and you can add as many extensions and just include their folder names in this array to include all of them. After installation, the extension is ready for use and should be listed in tailor.config.js file.
