[SalesForce] Create new record with default values LWC

I have also posted this idea to allow for such a feature in LWC.

It seems as of today, you cannot specify a record type id in LWC while utilizing NavigationMixin.Navigate to create a new record.

The attributes mentioned for standard__objectPage are only:

• actionName
• objectApiName
• filterName

There's no option available even on standard__recordPage which you could have utilized here. With all my experiences, something not documented is less likely to work (even if it does, it's not officially supported and could break at any point).

Your only option here could be to utilize an aura component composition and be able to use force:createRecord, as it does provide you a way to specify a recordTypeId.

Added based on comments

1. The getter recordTypeId will not be invoked unless you use it in HTML like {recordTypeId} OR by invoking it in JS like this.recordTypeId().

2. $recordTypeId is dynamic PROPERTY and not a method which will get value from method (getter).

3. You are not setting objectInfo anywhere so recordTypeId() will never return anything even if used in HTML.

Try below JS:

import { LightningElement, wire, api, track } from 'lwc';
import ORDER_OBJECT from '@salesforce/schema/Order';
import { getObjectInfo } from 'lightning/uiObjectInfoApi';
import { getPicklistValues } from 'lightning/uiObjectInfoApi';
import TYPE_FIELD from '@salesforce/schema/Order.Type';

export default class Poc extends LightningElement {
    @wire(getObjectInfo, { objectApiName: ORDER_OBJECT })
    getobjectInfo(result) {
        if (result.data) {
            const rtis = result.data.recordTypeInfos;
            this.recordTypeId = Object.keys(rtis).find((rti) => rtis[rti].name === 'Asia');
        }
    }

    @wire(getPicklistValues, { recordTypeId: '$recordTypeId', fieldApiName: TYPE_FIELD })
    orderTypeOption;
}

previous answer

In your example I see that you are using objectInfo but you are never fetching it.

Pls check below code sample:

import { LightningElement, wire, api } from 'lwc';
import ACCOUNT_OBJECT from '@salesforce/schema/Account';
import { getObjectInfo } from 'lightning/uiObjectInfoApi';

export default class Poc extends LightningElement {
    @wire(getObjectInfo, { objectApiName: ACCOUNT_OBJECT })
    getobjectInfo(result) {
        console.log('result => ', JSON.stringify(result.data.recordTypeInfos));
    }
}

Here you will get the record types through result.data.recordTypeInfos. You will see below data in recordTypeInfos.

{
  "012000000000000AAA": {
    "available": true,
    "defaultRecordTypeMapping": false,
    "master": true,
    "name": "Master",
    "recordTypeId": "012000000000000AAA"
  },
  "0120K000000TO5FQAW": {
    "available": true,
    "defaultRecordTypeMapping": false,
    "master": false,
    "name": "P1r",
    "recordTypeId": "0120K000000TO5FQAW"
  },
  "0120K000000TO5KQAW": {
    "available": true,
    "defaultRecordTypeMapping": true,
    "master": false,
    "name": "P2r",
    "recordTypeId": "0120K000000TO5KQAW"
  }
}
