FireCMS

sidebar_label: Collections

Once you have defined at least one entity schema, you can include it in a collection. You can find collection views as the first level of navigation in the main menu, or as subcollections inside other collections, following the Firestore data schema.

Check the full API reference in Entity collections

  • name The plural name of the view. E.g. 'products'.

  • relativePath Relative Firestore path of this view to its parent. If this view is in the root the path is equal to the absolute one. This path also determines the URL in FireCMS.

  • subcollections Following the Firestore document and collection schema, you can add subcollections to your entity in the same way you define the root collections.

  • defaultSize Default size of the rendered collection.

  • group Optional field used to group top level navigation entries under a navigation view. If you set this value in a subcollection it has no effect.

  • description Optional description of this view. You can use Markdown.

  • properties Properties displayed in this collection. If this property is not set every property is displayed.

  • excludedProperties Properties that should NOT get displayed in the collection view. All the other properties from the entity are displayed. It has no effect if the properties value is set.

  • indexes If you need to filter/sort by multiple properties in this collection, you need to create special indexes in Firestore. You can then specify here the indexes created.

  • initialFilter Initial filters applied to this collection.

  • initialSort Default sort applied to this collection. It takes tuples in the shape ["property_name", "asc"] or ["property_name", "desc"]

  • extraActions Builder for rendering additional components such as buttons in the collection toolbar. The builder takes an object with props entityCollection and selectedEntities if any are set by the end user.

  • pagination If enabled, content is loaded in batches. If false all entities in the collection are loaded. You can specify a number to specify the pagination size (50 by default) Defaults to true

  • additionalColumns You can add additional columns to the collection view by implementing an additional column delegate.

  • textSearchDelegate If a text search delegate is supplied, a search bar is displayed on top.

  • permissions You can specify an object with boolean permissions with the shape {edit:boolean; create:boolean; delete:boolean} to indicate the actions the user can perform. You can also pass a PermissionsBuilder to customize the permissions based on user or entity.

  • inlineEditing Can the elements in this collection be edited inline in the collection view. If this flag is set to false but permissions.edit is true , entities can still be edited in the side panel.

  • exportable Should the data in this collection view include an export button. You can also set an ExportConfig configuration object to customize the export and add additional values. Defaults to true

Additional columns

If you would like to include a column that does not map directly to a property, you can use the additionalColumns field, providing a AdditionalColumnDelegate, which includes an id, a title, and a builder that receives the corresponding entity.

In the builder you can return any React Component.

If you would like to do some async computation, such as fetching a different entity, you can use the utility component AsyncPreviewComponent to show a loading indicator.

export const productAdditionalColumn: AdditionalColumnDelegate = {
    id: "spanish_title",
    title: "Spanish title",
    builder: (entity: Entity<typeof productSchema>) =>
        <AsyncPreviewComponent builder={
            entity.reference.collection("locales")
                .doc("es")
                .get()
                .then((snapshot: any) => snapshot.get("name") as string)
        }/>
};

Subcollections

Subcollections are collections of entities that are found under another entity. For example, you can have a collection named "translations" under the entity "Article". You just need to use the same format as for defining your collection using the field subcollections.

Subcollections are easily accessible from the side view while editing an entity.

Filters

Filtering is enabled by default for string, numbers, booleans, timestamps and arrays. A dropdown is included in every column of the collection where applicable.

Since Firestore has limited querying capabilities, each time to apply a filter or new sort, the previous sort/filter combination gets reset by default (unless filtering, sorting by the same property).

If you need to enable filtering/sorting by more than one property at a time, you can specify the filters that you have enabled in your Firestore configuration. In order to do so, just pass the indexes configuration to your collection:

    const productsCollection = buildCollection({
    relativePath: "products",
    schema: productSchema,
    name: "Products",
    indexes: [
        {
            category: "asc",
            available: "desc"
        }
    ]
});

Permissions

You can define the edit, create and delete permissions at the collection level, also depending on the logged-in user.

buildCollection({
    relativePath: "products",
    schema: productSchema,
    name: "Products",
    permissions: ({ user }) => ({
        edit: true,
        create: true,
        delete: true
    })
});

Firestore does not support native text search, so we need to rely on external solutions. If you specify a textSearchDelegate to the collection view, you will see a search bar on top. The delegate is in charge of returning the matching ids, from the search string.

A delegate using AlgoliaSearch is included, where you need to specify your credentials and index. For this to work you need to set up an AlgoliaSearch account and manage the indexing of your documents. There is a full backend example included in the code, which indexes documents with Cloud Functions.

You can also implement your own TextSearchDelegate, and would love to hear how you come around this problem.
