app.post("/completions", async (req, res) => {
const funName = req.query.toolName;
console.log(funName, "funName");
res.write(data: ${JSON.stringify({ error: error.message })}\n\n);
res.write("data: [DONE]\n\n");
res.end();
})

This is written in expressjs but same thing is not working in nestjs.

NestJS uses Controllers to handle requests instead of directly defining route on app. like ExpressJS
Read more about controllers here: https://docs.nestjs.com/controllers

The equivalent in NestJS would be:

import { Controller, Post, Query } from '@nestjs/common';

@Controller("completions")
export class CompletionsController {
  @Post()
  handleCompletion(@Query("toolName") funName: string): string {
    console.log(funName, "funName");
    return `data: ${JSON.stringify({ error: "some error message" })}\n\n`
    // return "data: [DONE]\n\n"
  }
}

The one below is a middleground between ExpressJS and NestJS, but should also work fine.

import { Controller, Post, Req, Res } from '@nestjs/common';
import { Request, Response } from 'express';

@Controller("completions")
export class CompletionsController {
  @Post()
  handleCompletion(@Req() req: Request, @Res() res: Response) {
    const funName = req.query.toolName;
    console.log(funName, "funName");
    res.write(`data: ${JSON.stringify({ error: "some error message" })}\n\n`);
    res.write("data: [DONE]\n\n");
    res.end();
  }
}

# worthy reef How did you write it in Nest?

@Post('completions')
async createCompletion(
@Req() req: Request,
@Res() res: Response,
@Query('toolName') toolName: string,
) {
try {
console.log(req.body, req.query, 'req.body');
const fName = req.query.toolName;
const {
model = 'gpt-4o-mini',
messages,
modalities = ['text'],

    response_format,
    audio,
    stream = true,
    stream_options,
  } = req.body;

  if (!messages) {
    return res
      .status(400)
      .json({ detail: 'Missing messages in request body' });
  }

wait sending full code

Okay, so how is it "not working"?

#

Can you be specific? Because this is a lot to try and grok without context of what any error (or lackthere of with no response) might be happening

strong folio
#

I am not getting any error.

worthy reef
#

Are you getting any response? How are you making your request?

#

Any console logs? What debugging have you done?

See ,I have converted this express js code to nestjs.
the express js code working ,But the nestjs not.
