Import error related to types in a new project #4459
Description
context
While using the framework for the first time, I encountered a minor issue. It's not critical (in my case, I will simply install joi), but I thought you might want to be aware of it. Have a good day!
reproduction
In a new node.js project:
- install @hapi/hapi
- create a server.ts file with the content:
import Hapi from "@hapi/hapi";
async function init() {
const server = Hapi.server({
port: 3000,
host: 'localhost'
});
await server.start();
console.log('Server running on %s', server.info.uri);
};
init();- you get the following error:
> tsc
node_modules/@hapi/hapi/lib/types/route.d.ts:2:68 - error TS2307: Cannot find module 'joi' or its corresponding type declarations.
2 import { ObjectSchema, ValidationOptions, SchemaMap, Schema } from 'joi';
~~~~~
node_modules/@hapi/hapi/lib/types/server/server.d.ts:4:22 - error TS2307: Cannot find module 'joi' or its corresponding type declarations.
4 import { Root } from 'joi';
~~~~~
Found 2 errors in 2 files.
Errors Files
1 node_modules/@hapi/hapi/lib/types/route.d.ts:2
1 node_modules/@hapi/hapi/lib/types/server/server.d.ts:4note : npm i joi resolves the error.
a possible fix
Line 2 in 23d6550
could it be?
import { ObjectSchema, ValidationOptions, SchemaMap, Schema } from '@hapi/validate';

Yeah, hapi should not import typings directly from joi.
I don't know if your suggestion will work, and suspect that it can cause other issues when used.
The real solution is probably to expose those objects through a new generic, that can ideally be inferred.
