Separating Environments

In a production app you need to have different config versions for local development, staging and production. Here's how to do it with Typeconf.

Creating a config

Let's create a schema for our config:

model AgentConfig {
    prompt: string;
    searchAPIEndpoint: string;
}

Now let's create a default config under configs/agent.config.ts:

import { AgentConfig } from "./types/all.js";

const config: AgentConfig = {
  prompt: "You're an AI agent designed to do my work for me",
  searchAPIEndpoint: "https://google.com",
};

Environment based configs

Using this config we can create a separate config for each environment:

Dev:

// configs/dev/agent.config.ts
import { AgentConfig } from "../types/all.js";
import defaultConfig from "../agent.config.js";

const config: AgentConfig = {
  ...defaultConfig,
  searchAPIEndpoint: "http://localhost:1337",
};

export default config;

Staging:

// configs/dev/agent.config.ts
import { AgentConfig } from "../types/all.js";
import defaultConfig from "../agent.config.js";

const config: AgentConfig = {
  ...defaultConfig,
  prompt: "You're an agent designed to do my work for me and do my laundry",
};

export default config;

You should end up with this directory structure:

your-project/
├── configs/
│   ├── main.tsp
│   └── agent.config.ts
│   └── staging/
│       └── agent.config.ts
│   └── dev/
│       └── agent.config.ts
├── src/
└── next.config.js

Reading in your project

In you code you can just parametrize path depending on environment:

import { AgentConfig } from "./configs/types/all";
import { readConfig } from "@typeconf/react-sdk/server";

const env = (() => {
  switch (process.env.NODE_ENV) {
    case "production":
      return "";
    case "staging":
      return "staging";
    case "development":
      return "dev";
    default:
      return "dev";
  }
})();

const config: AgentConfig = readConfig(`configs/${env}/agent`);
