// https://github.com/whitep4nth3r/p4nth3rblog/blob/main/contentful/Events.js import ContentfulApi from "@contentful/Api"; const defaultOptions = { future: true, }; /* * Get all events -- future by default */ static async getEvents(options = defaultOptions) { // Calculate date_ASC for future events, or date_DESC for past events const order = options.future ? "date_ASC" : "date_DESC"; // Generate today's date const date = new Date(); // And format it to an ISO String const formattedDate = date.toISOString(); // Decide on the date filter to pass in as a string const dateFilter = options.future ? "date_gt" : "date_lt"; // Construct variables object to send with the HTTP POST request const variables = { date: formattedDate, order }; // Build the query const query = `query GetEvents($date: DateTime!, $order: [EventOrder]!) { eventCollection(where: {${dateFilter}: $date}, order: $order) { items { sys { id } date name link description timeTbc isVirtual image { url description height width } } } }`; // Call out to the base API call const response = await this.callContentful(query, variables); const eventCollection = response.data.eventCollection.items ? response.data.eventCollection.items : []; return eventCollection; }
