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:

here is index.js

i dont know what i am doing wrong
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(...)
For those who are using typescript and experience this problem: Be reminded that you need to include both ts
and js
file suffixes when specifying the entities-path:
ts
used when locally running with ts-node
js
used when having
built for production via tsc
.Code:
import * as path from 'path';
// ...
entities: [
// assuming _dirname is your project root
path.resolve(__dirname, '**/*.entity{.ts,.js}'),
],
I had the same problem for months and finally figured out what I was doing wrong.
When you import Entities, make sure the file names are EXACTLY matching. It's not going to throw any errors, but during the run time, it's going to throw the above error.
Ex. In the entity or model classes, if we import like this,
import { FooClass } from "./foo-Class.model";
it's different from
import { FooClass } from "./foo-class.model";
It won't show any errors, but when you try to call the table, it will show the exact same error.
