NodeSecure runtime configuration.

Requirements

• Node.js v18 or higher

Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn.

$ npm i @nodesecure/rc
# or
$ yarn add @nodesecure/rc

Usage example

read:

import * as RC from "@nodesecure/rc";

const configurationPayload = (
  await RC.read(void 0, { createIfDoesNotExist: true })
).unwrap();
console.log(configurationPayload);

write:

import assert from "node:assert/strict";
import * as RC from "@nodesecure/rc";

const writeOpts: RC.writeOptions = {
  payload: { version: "2.0.0" },
  partialUpdate: true,
};

const result = (await RC.write(void 0, writeOpts)).unwrap();
assert.strictEqual(result, void 0);

memoize/memoized:

import * as RC from "@nodesecure/rc";
import assert from "node:assert";

const configurationPayload = (
    await RC.read(void 0, { createMode: "ci" })
).unwrap()

RC.memoize(configurationPayload, { overwrite: true });

const memoizedPayload = RC.memoized();
assert.deepEqual(configurationPayload, memoizedPayload);

👀 .read and .write return Rust like Result object.

API

[!NOTE] If undefined, the location will be assigned to process.cwd().

read(location?: string, options?: readOptions): Promise< Result< RC, NodeJS.ErrnoException > >

interface createReadOptions {
  /**
   * If enabled, the file will be created if it does not exist on disk.
   *
   * @default false
   */
  createIfDoesNotExist?: boolean;
  /**
   * Generate a more or less complete configuration.
   *
   * @default `minimal`
   */
  createMode?: RCGenerationMode | RCGenerationMode[];
  /**
   * Automatically cache the configuration when enabled.
   *
   * @default false
   */
  memoize?: boolean;
}

export type readOptions = RequireAtLeastOne<
  createReadOptions,
  "createIfDoesNotExist" | "createMode"
>;

The createIfDoesNotExist argument can be ignored if createMode is provided.

import * as RC from "@nodesecure/rc";

const configurationPayload = (
  await RC.read(void 0, { createMode: "ci" })
).unwrap();
console.log(configurationPayload);

write(location?: string, options: writeOptions): Promise< Result< void, NodeJS.ErrnoException > >

By default the write API will overwrite the current payload with the provided one. When the partialUpdate option is enabled it will merge the new properties with the existing one.

/**
 * Overwrite the complete payload. partialUpdate property is mandatory.
 */
export interface writeCompletePayload {
  payload: RC;
  partialUpdate?: false;
}

/**
 * Partially update the payload. This implies not to rewrite the content of the file when enabled.
 **/
export interface writePartialPayload {
  payload: Partial<RC>;
  partialUpdate: true;
}

export type writeOptions = writeCompletePayload | writePartialPayload;

memoize(payload: Partial< RC >, options: memoizeOptions = {}): void

By default, the memory API overwrites the previous stored payload. When the OVERWRITE option is false, it merges new properties with existing properties.

export interface memoizeOptions {
  overwrite?: boolean;
}

The overwrite option is used to specify whether data should be overwritten or merged.

memoized(options: memoizedOptions): Partial< RC > | null

This method returns null, when the default value is null, otherwise, it returns the current value of memoizedValue.

export interface memoizedOptions {
  defaultValue: Partial<RC>;
}

If the defaultValue property is at null, then this value will be returned when memoized is called.

maybeMemoized(): Option< Partial< RC > >

Same as memoized but return an Option monad.

import * as RC from "@nodesecure/rc";

const memoized = RC.maybeMemoized()
  .unwrapOr({}); // Some default RC here

clearMemoized(): void

Clear/reset memoized RC

homedir(): string

Dedicated directory for NodeSecure to store the configuration in the os HOME directory.

import * as RC from "@nodesecure/rc";

const homedir = RC.homedir();

CONSTANTS

import assert from "node:assert/strict";
import * as RC from "@nodesecure/rc";

assert.strictEqual(RC.CONSTANTS.CONFIGURATION_NAME, ".nodesecurerc");

Generation Mode

We provide by default a configuration generation that we consider minimal. On the contrary, a complete value will indicate the generation with all possible default keys.

export type RCGenerationMode = "minimal" | "ci" | "report" | "scanner" | "complete";

However, depending on the NodeSecure tool you are working on, it can be interesting to generate a configuration with some property sets specific to your needs.

Note that you can combine several modes:

import * as RC from "@nodesecure/rc";

await RC.read(void 0, { createMode: ["ci", "report"] });

JSON Schema

The runtime configuration is validated using a JSON Schema: ./src/schema/nodesecurerc.json.

It can be retrieved via API if needed:

import * as RC from "@nodesecure/rc";

console.log(RC.JSONSchema);

The JSON schema is a composition of multiple definitions for each tool:

• ci
  • ciWarnings
  • contact
• report
  • reportChart
• scanner
