how to run angular 6 app with nodejs api on produc

问题:

Hi I am new to angular6

In development mode I have worked in angular 4200 port and node in different port (8080) in my operations. but now I want to move my app into production mode. for that I had build my angular project by using ng build command. after i get a dist folder is created on the root folder.

so i went to server.js file here I had add my static file

app.use(express.static(path.join(__dirname,'dist/MDProject')));

app.use('/',(req,res)=>{

    res.sendFile(path.join(__dirname,'dist/MDProject/index.html'))
});

click here to read my server.js file

by this when ever I redirect to my local host it is opening but in server.js side i didn't get any response.

when ever I try to login I am getting this error.

can anyone help me to solve this

回答1:

I think there are 2 things wrong here in your code.

First, update your code

From:-

app.use('/',(req,res)=>{

    res.sendFile(path.join(__dirname,'dist/MDProject/index.html'))
});    

To:- This code needs to be added just before your app.listen(app.get('port')) code

app.get('*', function(req, res) {
     res.sendfile('./public/MDProject/index.html'); 
     // load the single view file (angular will handle the page changes on the front-end)
});

Second, Serve your file from your public folder(In your case I think it is the dist folder). So update your code like this.

app.use(express.static(__dirname + '/dist/MDProject'));

回答2:

after I removed this line in my server.js file

app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');

and I paste this line before port creation.

app.use(express.static(path.join(__dirname,'dist/MDProject')));

app.use('/',(req,res)=>{

    res.sendFile(path.join(__dirname,'dist/MDProject/index.html'))
});

now it is working fine.

Use this to go to index page.

app.get('*', (req, res) => {
 res.sendfile('./public/MDProject/index.html');
})

with that you have to make folder in public in node

app.use('/', express.static('/dist/MDProject'))

Then in your app dist folder -> index.html

This is my working code. Let me know if you have still any issue. :)
