[英]node js webpack Undefined envioronment variable
嘿嘿,
我正在尝试使用 .env 文件来存储我正在使用的 API 的 API id 和密钥,但它不起作用。 我的 .env 文件位于我的工作目录的根目录以及 .gitignore 文件所在的存储库的根目录中。 它看起来像这样:
API_ID=XXXXXX
API_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXX
我安装了 dotenv 并在我的服务器目录中的 index.js 文件中这样称呼它:
const dotenv = require('dotenv');
dotenv.config();
然后在我的 apiCall.js 函数中,我尝试从 .env 文件中调用变量,如下所示:
const AYLIENTextAPI = require('aylien_textapi');
let textapi = new AYLIENTextAPI({
application_id: process.env.API_ID,
application_key: process.env.API_KEY
});
但 ID 和密钥显示为未定义。 我究竟做错了什么? 我真的很感激任何帮助。
谢谢,迈克
更新:
这是我的 webpack.dev.js 文件:
const path = require('path')
const webpack = require('webpack')
const HtmlWebPackPlugin = require("html-webpack-plugin")
const { CleanWebpackPlugin } = require('clean-webpack-plugin')
module.exports = {
entry: './src/client/index.js',
output : {
libraryTarget: 'var',
library: 'Client'
},
mode: 'development',
devtool: 'source-map',
stats: 'verbose',
module: {
rules: [
{
test: '/\.js$/',
exclude: /node_modules/,
loader: "babel-loader"
},
{
test: /\.scss$/,
use: [ 'style-loader', 'css-loader', 'sass-loader' ]
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./src/client/views/index.html",
filename: "./index.html",
}),
new CleanWebpackPlugin({
// Simulate the removal of files
dry: true,
// Write Logs to Console
verbose: true,
// Automatically remove all unused webpack assets on rebuild
cleanStaleWebpackAssets: true,
protectWebpackAssets: false
})
]
}
这是我的 package.json 文件:
{
"name": "example-project",
"version": "1.0.0",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node src/server/index.js",
"build-prod": "webpack --config webpack.prod.js",
"build-dev": "webpack --config webpack.dev.js"
},

}
弄清楚了。 我只能访问服务器端的环境变量。
