Pour certaines raisons, certains de mes modules doivent être des fichiers js
.
Je import
ts module dans mon fichier js
comme ceci:
resolver.js
:
import { Message } from '../../connectors/message';
// console.log('Message: ', Message);
const resolver = {
Query: {
sendMessage: (root, args, ctx) => {
console.log(args, ctx);
return Message.send('1', 'message');
}
}
};
export { resolver };
message.ts
:
const Message = {
send(id, type) {
return Promise.resolve({
recipient_id: '123',
message_id: '122'
});
}
};
export { Message };
J'utilise webpack
to et awesome-TypeScript-loader
pour compiler mes fichiers .ts
.
voici mon tsconfig.json
:
{
"compilerOptions": {
"target": "es6",
"lib": ["es6", "esnext"],
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"declaration": false,
"outDir": "dist",
"typeRoots": ["node_modules/@types"]
},
"files": ["src/main.ts"],
"exclude": ["node_modules"]
}
webpack.config.js
:
var nodeExternals = require('webpack-node-externals');
var webpack = require('webpack');
var path = require('path');
var fs = require('fs');
/* helper function to get into build directory */
var distPath = function(name) {
if (undefined === name) {
return path.join('dist');
}
return path.join('dist', name);
};
var webpack_opts = {
entry: './src/main.ts',
target: 'node',
output: {
filename: distPath('main.js'),
libraryTarget: 'commonjs2'
},
resolve: {
extensions: ['.ts', '.js'],
modules: ['node_modules', 'src']
},
plugins: [
new webpack.LoaderOptionsPlugin({
options: {
test: /\.ts$/,
ts: {
compiler: 'TypeScript',
configFileName: 'tsconfig.json'
},
tslint: {
emitErrors: true,
failOnHint: true
}
}
})
],
devtool: 'source-map',
module: {
loaders: [
{
test: /\.ts$/,
loaders: 'awesome-TypeScript-loader'
}
]
},
externals: [nodeExternals()]
};
module.exports = webpack_opts;
Mais j'ai eu cette erreur:
(function (exports, require, module, __filename, __dirname) { import { Message } from '../../connectors/message';
^^^^^^

Comment résoudre ceci? Merci.
- mise à jour v1 -
J'essaie de l'utiliser avec require
// import { Message } from '../../connectors/message';
const { Message } = require('../../connectors/message');
console.log('Message: ', Message);
const resolver = {
Query: {
sendMessage: (root, args, ctx) => {
console.log(args, ctx);
return Message.send('1', 'message');
}
}
};
export { resolver };
Mais j'ai toujours une erreur:

throw err;

J'ajoute l'extension de fichier .ts
au chemin:
const { Message } = require('../../connectors/message.ts');
toujours eu l'erreur:
export { Message };

mise à jour 3 : ajouter package.json
"devDependencies": {
"@types/faker": "^4.1.4",

},
essayez d'utiliser require('../../connectors/message')
la version de votre nœud ne prend pas en charge import
. use require à la place:
var Message = require('./path').Message;
- update - puisque vous essayez d'importer un fichier .ts
, vous devez l'écrire dans le chemin. comme ceci: require('./path.ts');
