@salesforce/core

What is @salesforce/core?

@salesforce/core is a powerful npm package designed to facilitate interaction with Salesforce's APIs and services. It provides a set of tools and utilities for managing Salesforce authentication, configuration, and API requests, making it easier for developers to build and manage Salesforce applications.

What are @salesforce/core's main functionalities?

Authentication

This feature allows you to authenticate to a Salesforce org using a username. The code sample demonstrates how to create an AuthInfo object and establish a connection to Salesforce.

const { AuthInfo } = require('@salesforce/core');

async function authenticate() {
  const authInfo = await AuthInfo.create({ username: 'your-username' });
  const connection = await authInfo.getConnection();
  console.log('Authenticated to Salesforce:', connection.instanceUrl);
}
authenticate();

Configuration Management

This feature provides tools for managing and retrieving Salesforce configuration settings. The code sample shows how to create a ConfigAggregator and retrieve the current configuration.

const { ConfigAggregator } = require('@salesforce/core');

async function getConfig() {
  const configAggregator = await ConfigAggregator.create();
  const config = configAggregator.getConfig();
  console.log('Salesforce Configuration:', config);
}
getConfig();

API Requests

This feature allows you to make API requests to Salesforce. The code sample demonstrates how to create a connection and perform a SOQL query to retrieve data from Salesforce.

const { Connection } = require('@salesforce/core');

async function querySalesforce() {
  const connection = await Connection.create({ authInfo: await AuthInfo.create({ username: 'your-username' }) });
  const result = await connection.query('SELECT Id, Name FROM Account');
  console.log('Query Result:', result.records);
}
querySalesforce();

Issues

Report all issues to the issues only repository.

Using TestSetup

The Salesforce DX Core Library provides a unit testing utility to help with mocking and sand-boxing core components. This feature allows unit tests to execute without needing to make API calls to salesforce.com.

See the Test Setup documentation.

Message Transformer

The Messages class, by default, loads message text during run time. It's optimized to do this only per file.

If you're using @salesforce/core or other code that uses its Messages class in a bundler (webpack, esbuild, etc) it may struggle with these runtime references.

src/messageTransformer will "inline" the messages into the js files during TS compile using https://github.com/nonara/ts-patch.

In your plugin or library,

yarn add --dev ts-patch

tsconfig.json

{
  ...
  "plugins": [{ "transform": "@salesforce/core/lib/messageTransformer", "import": "messageTransformer" }]
}

.sfdevrc.json, which gets merged into package.json

"wireit": {
    "compile": {
      "command": "tspc -p . --pretty --incremental",
      "files": [
        "src/**/*.ts",
        "tsconfig.json",
        "messages"
      ],
      "output": [
        "lib/**",
        "*.tsbuildinfo"
      ],
      "clean": "if-file-deleted"
    }
  }

Performance Testing

There are some benchmark.js checks to get a baseline for Logger performance. https://forcedotcom.github.io/sfdx-core/perf-Linux https://forcedotcom.github.io/sfdx-core/perf-Windows

You can add more test cases in test/perf/logger/main.js

If you add tests for new parts of sfdx-core outside of Logger, add new test Suites and create new jobs in the GHA perf.yml
