nestjs-devtools-loader v1.2.0

nestjs-devtools-loader

A helper package to easily enable/disable NestJS Devtools integration!

What it does

1. Add snapshot to true for NestFactory.create call
2. Import DevtoolsModule.register({ http: true, port: 8000 }) into the module passed to the NestFactory.create call if it was not imported already

that reduces the amount of boilerplate code you would have to write and
also allows us to not import that DevtoolsModule with no effort.

Install

You must have @nestjs/core (v9.3 or greater), @nestjs/devtools-integration and reflect-metadata installed!

npm install --save-dev nestjs-devtools-loader

Usage

Via preload module

You need to supply the --require nestjs-devtools-loader/register option to node
With NestJS's CLI, you can do:

nest start --exec "node -r nestjs-devtools-loader/register"
#                       ^~ an alias to --require

If you want to change the default options that are supplied to DevtoolsModule.register(), use the environment variable: NESTJS_DEVTOOLS_LOADER like this:

NESTJS_DEVTOOLS_LOADER='{"http":true,"port":3001}'

Programmatically

import { loader } from 'nestjs-devtools-loader'
// ...
// Before calling `NestFactory.create()`:
loader({ http: true, port: 8000 })

Disable

If you want to disable the loader while still injecting it into your app, set the environment variable NESTJS_DEVTOOLS_LOADER_DISABLED to "true"

Debug

If the env. var. DEBUG contains the string "nestjs-devtools-loader" like:
DEBUG=nestjs-devtools-loader
you'll see if the loader was injected or not.
