'How do I load a package from a package in a Lerna monorepo?

I have:

packages
 -models
   -package.json
   -....
 -server
   -src
     -index.ts
   -package.json

In my packages/server/package.json, I have:

  "scripts": {
    "dev": "ts-node src/index.ts"
  },
  "dependencies": {
    "@myapp/models": "../models",

In my packages/server/src/index.ts, I have:

import { sequelize } from '@myapp/models'

In my packages/models/src/index.ts, I have:

export type UserAttributes = userAttr


export { sequelize } from './sequelize';

but it gives me an error:

  Try `npm install @types/myapp__models` if it exists or add a new declaration (.d.ts) file containing `declare module '@myapp/models';`

 import { sequelize } from '@myapp/models'

How do I get this to work properly?

Solution 1:[1]

I don't know Lerna, but a good tool to deal with monorepos is npm link.

  1. cd packages/models
  2. npm link
  3. cd packages/server
  4. restore the version in dependencies "@myapp/models": "x.y.z",
  5. npm link @myapp/models

It should be enough.

Hope this helps.

lerna bootstrap first then yarn add <package_name> works Or lerna bootstrap first, then add the package and the target version then run yarn.

Solution 3:[3]

After you put in the dependencies in your server's package.json, you just need to run

lerna run --stream build

And your local should be able to access to it.
