You might come across a common requirement which is attempting to create a record using an LDS method.

Creating a new record using createRecord LDS record

It's not suggested to use this approach straight away, try to use one of the LDS tags to create a record. If the requirement needs bit of a customisation only then rely on using this method which is createRecord.

Here is the sample code that we can use to create a record using the LDS methods (which is createRecord()).

import { LightningElement } from "lwc";

//1. Import the method "createRecord" which is a named import
import { createRecord } from "lightning/uiRecordApi";

//2. Import the reference to Object and Fields
import ACCOUNT_OBJECT from "@salesforce/schema/Account";

import NAME_FIELD from "@salesforce/schema/Account.Name";
import INDUSTRY_FIELD from "@salesforce/schema/Account.Industry";
import RATING_FIELD from "@salesforce/schema/Account.Rating";


export default class ExploreCreateRecord extends LightningElement {

  name;
  industry;
  rating;

  handleChange(e) {
    if (e.target.name === "name") {
    
      //this is name input textbox
      this.name = e.target.value;
      console.log(this.name);
    } else if (e.target.name === "industry") {
    
      //this is industry input textbox
      this.industry = e.target.value;
      console.log(this.industry);
    } else if (e.target.name === "rating") {
    
      //this is rating input textbox
      this.rating = e.target.value;
      console.log(this.rating);
    }
  }

  handleClick() {
  
    //3. Map the data to the fields
    const fields = {};

    fields[NAME_FIELD.fieldApiName] = this.name;
    fields[INDUSTRY_FIELD.fieldApiName] = this.industry;
    fields[RATING_FIELD.fieldApiName] = this.rating;
        
        //4. Prepare config object with object and field API names 
    const recordInput = {
      apiName: ACCOUNT_OBJECT.objectApiName,
      fields: fields
    };
        
        //5. Invoke createRecord by passing the config object
    createRecord(recordInput).then((record) => {
      console.log(record);
    });
  }
}

exploreCreateRecord.js 

This is the template file used to capture the user input so that it can be used in creating a record.

<template>
  <lightning-input
    name="name"
    value={name}
    onchange={handleChange}
  ></lightning-input>
  <lightning-input
    name="rating"
    value={rating}
    onchange={handleChange}
  ></lightning-input>
  <lightning-input
    name="industry"
    value={industry}
    onchange={handleChange}
  ></lightning-input>

  <lightning-button label="Create" onclick={handleClick}></lightning-button>
</template>
