javascript - Enkelfilsbundle med NestJS + Typescript + Webpack + node_modules
Hur? Hur kan jag paketera ett NestJS-projekt inklusive node_module för en offlineapplikation?
webpack.config.js
const path = require('path');
module.exports = {
entry: path.join(__dirname, 'dist/main.js'),
target: 'node',
output: {
filename: 'compiled.js',
path: __dirname,
},
resolve: {
alias: {
node_modules: path.join(__dirname, 'node_modules'),
},
extensions: ['.js'],
},
};

Eller berätta för mig ett bra ramverk för att utveckla Windows-tjänster på Node.js som har scaffold och bygger till en enda fil. (Det är avgörande att paketet inkluderar alla beroenden, det vill säga hela node_modules-mappen, eftersom de datorer som denna tjänst ska installeras på inte har internet för att använda npm)
Svar #1
Jag fick det att fungera med följande webpack.config.js:
const path = require("path");
const webpack = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const WebPackIgnorePlugin =
{
checkResource: function(resource)
{
const lazyImports =
[
'@nestjs/microservices',
'@nestjs/microservices/microservices-module',
'cache-manager',
'class-transformer',
'class-validator',
'fastify-static',
];
if (!lazyImports.includes(resource))
return false;
try
{
require.resolve(resource);
}
catch (err)
{
return true;
}
return false;
}
};
module.exports =
{
mode: 'production',
target: 'node',
entry:
{
server: './src/main.ts',
},
devtool: 'source-map',
module:
{
rules:
[
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/,
},
],
},
resolve:
{
extensions: [ '.tsx', '.ts', '.js' ],
},
node: {
__dirname: false,
},
plugins:
[
new CleanWebpackPlugin(),
new webpack.IgnorePlugin(WebPackIgnorePlugin),
],
optimization:
{
minimize: false
},
performance:
{
maxEntrypointSize: 1000000000,
maxAssetSize: 1000000000
},
output:
{
filename: '[name].js',
path: path.resolve(__dirname, 'prod'),
},
};
Den del du behöver uppmärksamma här är IgnorePlugin. Nest använder lazy loading för vissa moduler, och webpack kan inte avgöra vilka. checkResource() gör de nödvändiga kontrollerna för de moduler som annars skulle generera fel när du försöker paketera din kod.
Du måste också sätta target: node-alternativet i din konfiguration så att webpack vet att vissa moduler som fs och net stöds nativt i Node (vilket inte är fallet när målet är en webbläsare).

@SergeySovgut: Jag är inte säker på om du har lyckats lägga till den anpassade konfigurationen med webpack än. Men här är en som jag använder för närvarande i mitt projekt
const nodeExternals = require('webpack-node-externals');
var terserPlugin = require('terser-webpack-plugin');
var uglifyJsPlugin = require('uglifyjs-webpack-plugin');
var dotEnvPlugin = require('dotenv-webpack');
module.exports = function(options) {
return {
...options,
entry: [ './src/main.ts'],
watch: false,
resolve: {
extensions: ['.ts', '.js', '.jade']
},
externals: [
nodeExternals(),
],
module: {
rules: [
...options.module.rules,
{
test: /\.handlebars$/,
loader: 'handlebars-loader',
options: {
knownHelpersOnly: false,
inlineRequires: /\/assets\/(:?images|audio|video)\//ig,
partialDirs: [path.join(__dirname, './src/views/email/partials')],
},
}
]
},
plugins: [
...options.plugins,
new webpack.HotModuleReplacementPlugin(),
new webpack.WatchIgnorePlugin([/\.js$/, /\.d\.ts$/]),
new dotEnvPlugin({
path: './config/development/.env',
safe: true,
systemvars: true,
silent: true,
defaults: false
}), new webpack.DefinePlugin({
'process.env.NODE_ENV': 'dev',
'process.env.DEBUG': 'debug'
}),new webpack.WatchIgnorePlugin([/\.js$/, /\.d\.ts$/]),
],
};
};
Kort sagt, kommer nest packad med webpack. Vissa av reglerna har förinställts, så till exempel har ts-loader autokonfigurerats för att transpila dina .ts-filer till .js-filer. Så allt vi behöver göra är att utöka de alternativ som redan tillhandahålls av nestjs och sedan skriva vår egen anpassade konfiguration ovanpå det.
Jag tror att de flesta av konfigurationerna är enkla och kan lätt hittas i webpack-dokumentationen
För att köra filen, konfigurera ett skript så här -> `"build:webpack:dev": "rimraf dist && nest build --watch --webpack webpack.dev.config.js"
Sedan kör npm run build:webpack:dev

Hoppas det hjälper
