node.js - Nepoznata ekstenzija datoteke ".ts" za TypeScript datoteku

Kada pokušam pokrenuti svoju aplikaciju na Heroku, dobio sam sljedeći stack trace. To je samo osnovna ts.app kao što vidite s ts-node i nodemon.

Zaista me zanima što će odgovor biti.

Odgovor #1

Po mom mišljenju, ovaj odgovor je najbolji. https://stackoverflow.com/a/74608156/12894626

ukratko; Nakon godina pokušaja da ts-node radi, jednostavno koristite tsx koji radi odmah nakon instalacije.

npm i -D tsx
npx tsx src/index.ts

npm: https://www.npmjs.com/package/tsx

Ima 400 tisuća tjednih preuzimanja u vrijeme pisanja i broj raste.

Odgovor #2

Uklonite "type": "module" iz package.json

https://github.com/TypeStrong/ts-node/issues/935

https://github.com/TypeStrong/ts-node/issues/1007#issuecomment-1163471306

Ako ne želite ukloniti "type": "module" (na primjer, ako koristite import izjave u vašim .ts datotekama što omogućuje zaključivanje tipova iz modula), tada možete koristiti sljedeću opciju u tsconfig.json:

{
  "compilerOptions": {
    "esModuleInterop": true,
  }
}

I onda možete pokrenuti server s konfiguracijom koristeći ts-node.

Instaliraj :

npm install -g ts-node

Trči :

ts-node-esm my_server.ts

Odgovor #3

koristiti

node --loader ts-node/esm ./my-script.ts

// OR

ts-node --esm ./my-script.ts

umjesto

ts-node ./my-script.ts

Odgovor #4

OŽUJAK 2022

UPORABA: Node 16.6.2, ts-node v 10.7.0

Meni je pomoglo imati "type": "module" u package.json, i dodati:

node --experimental-specifier-resolution=node --loader ts-node/esm ./src/app.ts

tsconfig.json:

{
    "compilerOptions": {
      "module": "ESNext",
      "esModuleInterop": true,
      "target": "ESNext",
      "moduleResolution": "Node",
      "outDir": "dist",
      "forceConsistentCasingInFileNames": true,
      "noFallthroughCasesInSwitch": true,
      "isolatedModules": false,
      "strict": true,
      "noImplicitAny": true,
      "useUnknownInCatchVariables": false,
      "inlineSourceMap": true
    },
    "ts-node": {
        "esm": true
    },
    "lib": ["esnext"]
}

Zasluge idu @FelipePlets za korisni odgovor ovdje

UREDI Možda ćete htjeti koristiti opciju koja nije esnext, prema ts dokumentaciji:

Posebna vrijednost ESNext odnosi se na najnoviju verziju koju podržava vaša verzija TypeScripta. Ovu postavku treba koristiti oprezno, jer ne znači isto među različitim verzijama TypeScripta i može učiniti nadogradnje manje predvidljivima.

Odgovor #5

Uklanjanje "type": "module" iz package.json i dodavanje:

  "compilerOptions": {
    "module": "CommonJS"
  },

U tsconfig.json to je popravilo za mene.

Odgovor #6

Rješenje Jedan

Uklonite "type": "module" iz package.json ako je dodano
U tsconfig.json pod compilerOptions postavite svojstvo module na CommonJS module: "CommonJS" i moduleResolution: "Node"

Rješenje Dva

ako prvi nije uspio, ili iz nekog razloga morate zadržati `module: "ESNext"`

1- Dodajte "type": "module" u package.json

2- Instalirajte ts-node npm i -g ts-node

3- Idite na tsconfig.json i dodajte sljedeće:

{
    "compilerOptions": {
        "module": "ESNext",
        "moduleResolution": "Node",
        /* ... your props ... */
    },
    "ts-node": {
        "esm": true
    }
}

4- Pokrenite ts-node fileName.ts

Odgovor #7

Pokušajte dodati ovo u svoj tsconfig.json

"ts-node": {
    "esm": true,
    "experimentalSpecifierResolution": "node",
}

Uspio sam popraviti s tsconfig.json koji je izgledao otprilike ovako:

{
  "compilerOptions": {
    "target": "es2022",
    "lib": ["ES2022"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noFallthroughCasesInSwitch": true,
    "module": "ES2022",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
  },
  "exclude": [
    "node_modules",
  ],
  "ts-node": {
    "esm": true,
    "experimentalSpecifierResolution": "node",
  }
}

Odgovor #8

Prvi put sam naišao na ovaj problem vjerojatno prije više od godinu dana, i ts-node ga još uvijek nije popravio. Nijedno od gore navedenih rješenja nije mi uspjelo, i čini se da sam probao sve.

Jednostavno sam pribjegao korištenju tsc --outDir out file.ts i zatim normalno pokrenuo datoteku s node out/file.js, a zatim dodao out u .gitignore.

Ideja iza ts-node je prekrasna, samo stvarno frustrira kada ne može rukovati naizgled jednostavnim primjerima poput ovog. Isprike što rješenje ne koristi ts-node, ali ga nisam uspio natjerati da radi.

Odgovor #9

Napravio sam neke promjene u svom package.json i tsconfig.json. Napokon, uspjelo mi je!

Dodajte "type": "module" u package.json
Otkomentirajte odjeljak "moduleResolution": "node" u vašem tsconfig.json
Promijenite odjeljak "module" u "ESNEXT" u vašem tsconfig.json
Zatim samo pokrenite glavni skript s ovim čvorom --loader ts-node/esm .\index.ts

Odgovor #10

Nakon nekih eksperimenata s mojom ts-node/puppeteer konfiguracijom došao sam do ovoga:
