nodejs的顶尖开源项目

1、load env文件

import { config as loadDotenv } from "dotenv";

loadDotenv();

 

或者

import "dotenv/config";

 

2、nodejs的数据的输入输出 

import { createInterface } from "node:readline/promises";

import { stdin as input, stdout as output } from "node:process";

 const rl = createInterface({ input, output });

const userText = (await rl.question("你: ")).trim();

if (["exit", "quit", "q"].includes(userText.toLowerCase())) {

        break;

      }

   console.log(`AI: ${text || "（未返回文本内容）"}\n`);

 

3、获取文件的拓展名

import { extname } from "node:path";

 

     const suffix = extname(filePath).toLowerCase();

      if (suffix !== ".md" && suffix !== ".txt") {

        continue;

      }

4、获取文件的目录

import { resolve } from "node:path";

const KNOWLEDGE_BASE_DIR = resolve(process.cwd(), "knowledge_base");

5、根据文件目录 遍历文件

walkFiles(KNOWLEDGE_BASE_DIR);

function walkFiles(dir: string): string[] {

  const files: string[] = [];

  for (const entry of readdirSync(dir, { withFileTypes: true })) {

    const fullPath = resolve(dir, entry.name);

    if (entry.isDirectory()) {

      files.push(...walkFiles(fullPath));

    } else {

      files.push(fullPath);

    }

  }

  return files;

}

6、文件读取

import { existsSync, readFileSync } from "node:fs";

function loadTrainingExamples(maxExamples = 20): TrainingExample[] {

    if (!existsSync(TRAINING_DATA_PATH)) {

        return [];

    }

    return readFileSync(TRAINING_DATA_PATH, "utf-8")

        .split(/\r?\n/)

        .map((line) => line.trim())

        .filter(Boolean)

        .flatMap(parseTrainingExample)

        .slice(0, maxExamples);

}

6、读取env文件

const apiKey = process.env.OPENAI_API_KEY?.trim();

    const baseURL = process.env.OPENAI_BASE_URL?.trim();

    const model = process.env.MODEL_NAME?.trim() || "qwen-plus";

 

 7、抛出异常

    if (!apiKey || !baseURL) {

        throw new Error("缺少 OPENAI_API_KEY 或 OPENAI_BASE_URL 配置");

    }
