'number' only refers to a type, but is being used as a value here

February 20, 2022

src/db/models/point.ts:10:11 – error TS2693: ‘number’ only refers to a type, but is being used as a value here.

const PointSchema: Schema = new Schema({
  id: {
    type: String,
    required: true,
    unique: true,
    index: true,
  },
  point: {
    type: number,
    required: true,
  },
});

export interface PointProp extends Document {
  id: string;
  point: number;
}

export default model<PointProp>('point', PointSchema);

>Solution :

You are using a TypeScript type inside an object, as value, just as what the error says. You should have given more info, but I am guessing you are working with Mongoose. In that case, number (the TypeScript type) should be Number (the object)

const PointSchema: Schema = new Schema({
  id: {
    type: String,
    required: true,
    unique: true,
    index: true,
  },
  point: {
    type: Number, // <---
    required: true,
  },
});
