RepositoryNotFoundError : Typeorm

Question

I am trying to get the following example working https://github.com/typeorm/javascript-example/tree/master/src/app3-es6

I am running into the following error

Error at new RepositoryNotFoundError (...\node_modules\typeorm\connection\error\RepositoryNotFoundError.js:24:23) at Connection.findRepositoryAggregator (...\node_modules\typeorm\connection\Connection.js:513:19) at Connection.getRepository (...\node_modules\typeorm\connection\Connection.js:405:21) at ...\index.js:27:37

name: 'RepositoryNotFoundError',
  message: 'No repository for "Post" was found. Looks like this entity is not registered in current "default" connection?'

here is index.js

const typeorm = require("typeorm"); // import * as typeorm from "typeorm";
const Post = require("./model/Post"); // import {Post} from "./model/Post";
// import Post from './model/Post.js';
const Category = require("./model/Category"); // import {Category} from "./model/Category";

typeorm.createConnection({
    driver: {
        type: "oracle",
        host: "localhost",
        port: 1521,
        username: "uname",
        password: "pwd",
        sid: "dev"
    },
    entities: [
        __dirname + "/entity/*.js"
    ],
    autoSchemaSync: true
}).then(function (connection) {
    console.log(connection);

    let post = new Post.Post();
    post.title = "Control flow based type analysis";
    post.text = "TypeScript 2.0 implements a control flow-based type analysis for local variables and parameters.";
    post.categories = [new Category.Category(0, "TypeScript"), new Category.Category(0, "Programming")];

    let postRepository = connection.getRepository(Post.Post);
    postRepository.persist(post)
        .then(function(savedPost) {
            console.log("Post has been saved: ", savedPost);
            console.log("Now lets load all posts: ");

            return postRepository.find();
        })
        .then(function(allPosts) {
            console.log("All posts: ", allPosts);
        });
}).catch(function(error) {
    console.log("Error: ", error);
});

Post.js in /model/

/*export */ class Post {
    constructor(id, title, text, categories) {
        this.id = id;
        this.title = title;
        this.text = text;
        this.categories = categories;
    }
}

module.exports = {
    Post: Post
};

Category.js

/*export */ class Category {
    constructor(id, name) {
        this.id = id;
        this.name = name;
    }
}

module.exports = {
    Category: Category
};

PostSchema.js in /entity/

const Post = require("../model/Post"); // import {Post} from "../model/Post";
const Category = require("../model/Category"); // import {Category} from "../model/Category";
const PostSchema = {
    target: Post,
    columns: {
        id: {
            primary: true,
            type: "int",
            generated: true
        },
        title: {
            type: "string"
        },
        text: {
            type: "text"
        }
    },
    relations: {
        categories: {
            target: Category,
            type: "many-to-many",
            joinTable: true,
            cascadeInsert: true
        }
    }
};

module.exports = {
    PostSchema: PostSchema
};

CategorySchema.js

const Category = require("../model/Category"); // import {Category} from "../model/Category";
const CategorySchema = {
    target: Category,
    columns: {
        id: {
            primary: true,
            type: "int",
            generated: true
        },
        name: {
            type: "string"
        }
    }
};

module.exports = {
    CategorySchema: CategorySchema
};

i dont know what i am doing wrong

Answer 1

It looks like your entity import is not working. If you import via the wildcard:

entities: [
    __dirname + "/entity/*.js"
],`

Make sure your model is compiled to js. You also could just import

createConnection({ 
    ..., 
    entities: [
        Post,
        ...
    ],}).then(...)
