running project with js error

[idkjs]

I've stripped out the ts and replaced with js but cant get index.js to read them i think.

After running prisma deploy and then yarn dev i'm getting the following error:

[nodemon] starting `node -r dotenv/config src/index.js`
/Users/prisc_000/code/BHYV/airbnb-server/node_modules/graphql-yoga/node_modules/graphql-tools/dist/schemaGenerator.js:311

[nodemon] app crashed - waiting for file changes before starting...

This is index.js. Error is on const server on line 5.

const { GraphQLServer } = require('graphql-yoga')
const { Prisma } = require('./generated/prisma')
const { resolvers, fragmentReplacements } = require('./resolvers')

const server = new GraphQLServer({
  typeDefs: './src/schema.graphql',
  resolvers,
  context: req => ({
    ...req,
    db: new Prisma({
      // typeDefs: 'src/generated/prisma.graphql',
      fragmentReplacements,
      endpoint: process.env.PRISMA_ENDPOINT,
      secret: process.env.PRISMA_SECRET,
      debug: true,
    }),
  }),
})

server.start(({ port }) =>
  console.log(`Server is running on http://localhost:${port}`),
)

Any idea on what is going on here?

graphqlconfig.yml

projects:
  app:
    schemaPath: src/schema.graphql
    includes:
      - 'queries/{booking,queries}.graphql'
    extensions:
      endpoints:
        default: 'http://localhost:4000'
  prisma:
    schemaPath: "src/generated/prisma.graphql"
    includes: ["database/seed.graphql"]
    extensions:
      prisma: database/prisma.yml
      prepare-binding:
        output: src/generated/prisma.js
        generator: prisma-js

figured it out. working repo is https://github.com/idkjs/graphql-server-example

Converting from typescript to js

1. First change all file names to js then remove any typings. vscode will tell you where they are in problems tab.

2. deps: yarn add babel-cli babel-preset-env babel-plugin-transform-object-rest-spread -D
   To get this to run I had to change the start scripts and add "babel" property to package.json

  "scripts": {
    ...
    "babel-node": "babel-node --presets=env",
    "start": "nodemon -e js,graphql -x babel-node src/index.js",
    "build": "rm -rf dist && graphql prepare",
    ...
  },
  ...
    "babel": {
    "presets": ["env"],
    "plugins": ["transform-object-rest-spread"]
  },

3. Set up dotenv for es6 by adding src/env.js then calling it from src/index.js. solution in this issue
   See src/env.js and src/index.js
4. Change graphqlconfig.yml prepare-bindings to:

prepare-binding:
        output: src/generated/prisma.js
        generator: prisma-js
