Load configuration from file

Ts.ED doesn't provide solution to load configuration from files. Because, there is many solution to achieve this, we consider this part as the developer responsibility.

By using node-config or dotenv, it's possible to load your configuration from file as following:

dotenv

import {$log} from "@tsed/logger";
import {PlatformExpress} from "@tsed/platform-express";
import dotenv from "dotenv";
import {Server} from "./Server.js";

dotenv.config({path: "/full/custom/path/to/your/env/vars"});

async function bootstrap() {
  try {
    $log.debug("Start server...");
    const platform = await PlatformExpress.bootstrap({
      rootModule: Server,
      envs: process.env
    });

    await platform.listen();
    $log.debug("Server initialized");
  } catch (er) {
    $log.error(er);
  }
}

bootstrap();

dotenv-flow

import {$log} from "@tsed/logger";
import {PlatformExpress} from "@tsed/platform-express";
import dotenv from "dotenv-flow";
import {Server} from "./Server.js";

dotenv.config();

async function bootstrap() {
  try {
    $log.debug("Start server...");
    const platform = await PlatformExpress.bootstrap({
      rootModule: Server,
      envs: process.env
    });

    await platform.listen();
    $log.debug("Server initialized");
  } catch (er) {
    $log.error(er);
  }
}

bootstrap();

node-config

import {$log} from "@tsed/logger";
import {PlatformExpress} from "@tsed/platform-express";
import {Server} from "./Server.js";

const rootDir = __dirname;

// /!\ configuration file must be outside of your src directory
process.env["NODE_CONFIG_DIR"] = `${rootDir}/../config`;
const config = require("config");

async function bootstrap() {
  try {
    $log.debug("Start server...");
    const platform = await PlatformExpress.bootstrap({rootModule: Server, ...config /* or config.util.toObject() */});

    await platform.listen();
    $log.debug("Server initialized");
  } catch (er) {
    $log.error(er);
  }
}

bootstrap();
