next.js with typescript decorators

[djleonskennedy]

Hello all!

I need to use api/route as graphql endpoint with type-graphql (to avoid to run another server)

How to enable next's babel works with decorators,
tried tons of solution! result TypeError: Reflect.metadata is not a function

.babelrc:

{
  "presets": ["next/babel"],
  "plugins": [["@babel/plugin-proposal-decorators", { "legacy": true }]]
}

Correct config is:

{  
  "presets": ["next/babel"],  
    "plugins": [   
      "babel-plugin-transform-typescript-metadata",    
      ["@babel/plugin-proposal-decorators", { "legacy": true }],    
      ["@babel/plugin-proposal-class-properties", { "loose": true }]  
]}
