typescriptimportscriptingtsconfigtsconfig-paths

How can I get a Typescript script to use the paths defined in tsconfig?

In my NodeJS/Typescript project, I created a script database-init.script.ts that I run to initialize the database with sample data.

My package.json looks like this:

{
   "name": "myproject",
   ....
   "scripts": {
      ...
      "mongodb-setup": "tsc ./scripts/mongodb-setup.ts && node ./scripts/mongo-setup.js"
      
}

The problem is that the script imports some files that themselves utilize tsconfig paths shortcuts. For example some files have

import {AccountSchema} from '@schemas/account.schema'
...

My script fails because it doesn't recognize these. It gives me

error TS2307: Cannot find module '@schemas/account.schema' or its corresponding type declarations.

1 import {AccountSchema} from '@schemas/account.schema";

How can I get a script to recognize tsconfig-defined paths, without compiling the entire project?

Solution

  • It seems you are looking for ts-node.

    {
  "name": "myproject",
  ....
  "devDependencies": {
    ...
    "ts-node": "*"
  },
  "scripts": {
    ...
    "mongodb-setup": "node -r ts-node/register ./scripts/mongo-setup.ts"
  }
}
