修复有关 Webpack 加载程序处理的导入的 TypeScript 警告?
Fix TypeScript warning about imports handled by Webpack loaders?
我正在使用 Svelte、Webpack 和 TypeScript 建立一个新项目。它基于 this template,并且 运行 scripts/setupTypeScript.js
脚本在初始设置后切换到 TypeScript。
当尝试导入 不是 TypeScript 文件的资源时,VSCode 和 TypeScript 显示有关它们的错误:
import myContent from './some-file.txt';
// -> Cannot find module './some-file.txt' or its corresponding type declarations.ts(2307)
从技术上讲这是可行的,但错误很嘈杂,似乎阻止了实时重新加载。有没有办法让 TypeScript 忽略这些导入并相信 Webpack 会处理它们?其中一些是二进制文件,所以我也不能将它们 copy/paste 放入 .ts
文件中。
Webpack 和 TS 配置如下:
webpack.config.js:
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const path = require('path');
const sveltePreprocess = require('svelte-preprocess');
const mode = process.env.NODE_ENV || 'development';
const prod = mode === 'production';
module.exports = {
entry: {
'build/bundle': ['./src/main.ts']
},
resolve: {
alias: {
svelte: path.dirname(require.resolve('svelte/package.json'))
},
extensions: ['.mjs', '.js', '.ts', '.svelte'],
mainFields: ['svelte', 'browser', 'module', 'main']
},
output: {
path: path.join(__dirname, '/public'),
filename: '[name].js',
chunkFilename: '[name].[id].js'
},
module: {
rules: [
{
test: /\.ts$/,
loader: 'ts-loader',
exclude: /node_modules/
},
{
test: /\.svelte$/,
use: {
loader: 'svelte-loader',
options: {
compilerOptions: {
dev: !prod
},
emitCss: prod,
hotReload: !prod,
preprocess: sveltePreprocess({ sourceMap: !prod })
}
}
},
{
test: /\.css$/,
use: [
MiniCssExtractPlugin.loader,
'css-loader'
]
},
{
test: /\.(txt)$/,
use: ['raw-loader']
},
{
test: /\.(ttf|wasm)$/,
use: ['file-loader']
},
{
// required to prevent errors from Svelte on Webpack 5+
test: /node_modules\/svelte\/.*\.mjs$/,
resolve: {
fullySpecified: false
}
}
]
},
mode,
plugins: [
new MiniCssExtractPlugin({
filename: '[name].css'
})
],
devtool: prod ? false : 'source-map',
devServer: {
hot: true
}
};
tsconfig.json:
{
"extends": "@tsconfig/svelte/tsconfig.json",
"include": ["src/**/*.ts", "src/node_modules/**/*.ts"],
"exclude": ["node_modules/*", "__sapper__/*", "static/*"]
}
添加一个包含以下内容的 global.d.ts
文件,并确保它被您的 include
选中:
declare module "*.txt";
这告诉 TS“任何以 .txt
结尾的导入都可以,将其视为 any
”。或者,使用另一种类型导出默认值:
declare module "*.txt" {
const content: string;
export default content;
}
