Wire to Promise converter

[JackVeromeev]

API

• Mixin WirePromiseMixin
• method to capture the data from wire
  @wire(getRecord, {...props}) setSomeRecord(recordData) { this.setWire('some record', recordData); }
• method to get the data from storage
  this.getWire('some record') => Promise

Solution

class A {

    contactRecordTypeId;
  
    @wire(getObjectInfo, {objectApiName: CONTACT})
    setContactData(response) { this.setWire("WIRE_CONTACT", response); }
    
    @wire(getCurrentPageRef)
    setPageRef(ref) { this.setWire("PAGE_REF", ref); }
    
    @wire(getPicklistOptions, {fieldApiName: CONTACT_TYPE, recordTypeId: "$contactRecordTypeId")
    setPicklist(response) { this.setWire("WIRE_PICKLIST", response); }
  
    async init() {
        const contactData = await this.getWire("WIRE_CONTACT");
        this.contactRecordTypeId = contactDdata.defaultRecordTypeId;
        const pageRef = await this.getWire("PAGE_REF");
        const picklistOptions = await this.getWire("WIRE_PICKLIST");
        // now you can operate there with all data you need
    }
}

PREVIOUS Solution draft

class A {
    someProp;
    @wire(getSomeProp)
    setSomeProp({data, error}) {
        // proto for "setSomeRecord"
        if (data) {
            this.someProp = data;
            this.somePropAwaitList.forEach(([resolve]) => resolve(this.someProp));
        }
        if (error) {
            this.somePropAwaitList.forEach(([resolve, reject]) => reject(error));
            console.error(error);
        }
    }
    somePropAwaitList = [];
    awaitSomeProp = () => { // proto for "getWired"
        if (this.someProp !== undefined) {
            return Promise.resolve(this.someProp);
        } else {
            return new Promise((resolve, reject) => {
                this.somePropAwaitList = [...this.somePropAwaitList, [resolve, reject]];
            });
        }
    }
}
