我在https://github.com/frankhale/electron-with-express上阅读并尝试了类似的示例,但我仍然不明白如何将Express应用转换为Electron
如何在现有Express应用程序中使用Electron?
以这个Express应用程序为例:
app.js
var express = require("express");
var app = express();
var request = require("request");
app.set("view engine", "ejs");
app.get("/", function(req, res) {
res.render("search");
});
app.get("/results", function(req, res){
var query = req.query.search;
var url = "https://yts.am/api/v2/list_movies.json?sort=seeds&limit=15&query_term='" + query + "'";
request(url, function(error, response, body){
var data = JSON.parse(body);
if(!error && response.statusCode == 200){
//res.send(data["data"]["movies"][0]["title"]);
res.render("results", {data: data});
//["movies"][0]["title"]
}
else
console.log(data);
});
});
app.listen(process.env.PORT, process.env.IP, function(){
console.log("IMDB server has started");
});
search.ejs
Search for a movie
<form action="results" method="GET">
<input type="text" placeholder="search term" name="search">
<input type="submit">
</form>
results.ejs
Results page
<ul>
<% data["data"]["movies"].forEach(function(movie){ %>
<li>
<strong><%= movie["title"]%></strong> - <%= movie["year"]%>
</li>
<% }) %>
</ul>
<a href="/">Search again</a>

在电子main.js
文件中,您应该require
文件app.js
以启动Express应用程序,然后创建一个新的BrowserWindow
实例并加载您Express应用程序正在监听。
请注意,您将不得不在Electron中对IP和PORT进行硬编码,或者从Express中导出它们并将其导入到Electron main.js
脚本中。
./ main.js
const { BrowserWindow, app } = require('electron')
require('./app.js')
let mainWindow = null
function main() {
mainWindow = new BrowserWindow()
mainWindow.loadURL(`http://localhost:3000/`)
mainWindow.on('close', event => {
mainWindow = null
})
}
app.on('ready', main)
./ package.json
{
"name": "your-app-name",
"version": "1.0.0",
"description": "A description of your application",
"main": "main.js",
"scripts": {
"start": "electron ."
},
"repository": "https://github.com/link/to/repo",
"keywords": [ "some","keywords" ],
"author": "You",
"license": "Your License",
"dependencies": {
"ejs": "^2.6.1", // required for your specific example where `ejs` package is used
"electron": "^3.0.9",
"express": "^4.16.4"
}
}
然后,您要确保node_modules
目录与main.js
和package.json
在同一目录中。
最后,您可以使用以下命令启动Express / Electron应用程序:
> npm start
如果您的Express应用程序与Electron不在同一目录中,则必须设置views
的Express目录:
app.js
var path = require('path')
var request = require("request");
var express = require("express");
var app = express();
app.set('views', path.join(__dirname, '/views'));
...
/views
是相对于app.js
的目录,其中包含您的视图。
