mapResponse not found in module

[mjjabarullah]

What version of Elysia is running?

1.2.6

What platform is your computer?

Microsoft Windows NT 10.0.22635.0 x64

What steps can reproduce the bug?

After upgrading elysis version 1.2.6 i got mapResponse not found in module. I have removed bun.locknb file and node_modules file and installed again. Nothing works

What is the expected behavior?

bun run dev: should start elysia server

What do you see instead?

Additional information

No response

Have you try removing the node_modules and bun.lockb and try again yet?

I have tried

After a deep investigation in my code "elysia-compression" plugin causes this issue. I have replaced the package with "elysia-compress" same issue occurs

Seems like plugin doesn't have been updated to 1.2 yet. You can either:

1. wait for the plugin to update to 1.2
2. force the plugin to use Elysia 1.2 with override and it might work

{
    "override": {
        "elysia": "1.2.6"
    }
}

Ultimately, should be solved once the plugin has been updated to 1.2

It seems resolving this issue takes some time.

Here is a temporary workaround that was good enough for us:

export const compression = new Elysia({ name: 'compressResponses' })
  .mapResponse(({ request, response, set }) => {
    const isJson = typeof response === 'object'
    const compressionRequested = request.headers.get('Accept-Encoding')?.includes('gzip')

    const text = isJson ? JSON.stringify(response) : (response?.toString() ?? '')

    // Only compress if content is larger than 2KB and compression is requested
    if (!compressionRequested || text.length < 2048) {
      return response as Response
    }

    set.headers['Content-Encoding'] = 'gzip'

    return new Response(Bun.gzipSync(new TextEncoder().encode(text)), {
      headers: {
        'Content-Type': `${isJson ? 'application/json' : 'text/plain'}; charset=utf-8`,
      },
    })
  })
  .as('plugin')

It's based on this example but works with swagger plugin and has a sensible minimal threshold (2kb)

This has no configuration options and it only supports gzip. If you need to actually also compress blobs see this gist. but i skipped it here for brevity

Usage, very similar to elysia-compress:

const app = new Elysia()
 .use(compression)
 .get('/', () => ({ hello: 'world' }))

Since it uses blocking gzipSync, it's definitely not ideal for all usecases,but might be an option for some
