Hi, thanks for your book. I have been battling with this error TypeError: db.models[key].associate is not a function. I have tried to resolve but all to no avail. Can you help out?

When I run your code about mocha test,in the directory test/routes/ if a test file follow closely token.js, it will always throw an error:

Routes: Users
    GET /user
      status 200
Unhandled rejection SequelizeUniqueConstraintError: Validation error
    at Query.formatError (/home/jadestrong/Documents/building-apis-with-nodejs/ntask-api/node_modules/sequelize/lib/dialects/sqlite/query.js:337:14)
    at Statement.afterExecute (/home/jadestrong/Documents/building-apis-with-nodejs/ntask-api/node_modules/sequelize/lib/dialects/sqlite/query.js:112:29)
    at Statement.replacement (/home/jadestrong/Documents/building-apis-with-nodejs/ntask-api/node_modules/sqlite3/lib/trace.js:20:31)

        1) "before each" hook for "returns an authenticated user"


  11 passing (4s)
  1 failing

  1) Routes: Users "before each" hook for "returns an authenticated user":
     Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.

after test,I found the reason is :

describe("Routes: Token", () => {
  const Users = app.db.models.Users;
  describe("POST /token", () => {
    beforeEach(done => {
      Users
        .destroy({where: {}})
        .then(() => Users.create({
          name: "John",
          email: "[email protected]",
          password: "12345"
        }))
        .then(done());   // here should be `.then(() => done())`
    });

You can test it, and change the book's content about it.
English is not good, forgive me

Hello,

many thanks for the tutorial, this is very very helpful for a newbie like me. I am able to follow the complete code and able to make it run. The only issue I am facing is related to test.

I downloaded the repository and installed all packages.
entered the following command
npm test

D:\XAMPP\htdocs\nodewebservice\building-apis-with-nodejs-master\ntask-api>npm test

> [email protected] test D:\XAMPP\htdocs\nodewebservice\building-apis-with-nodejs-master\ntask-api
> SET NODE_ENV=test mocha test/**/*.js

D:\XAMPP\htdocs\nodewebservice\building-apis-with-nodejs-master\ntask-api>

There is no test executed. Please help me solve this,

This is not an issue, per se, but it's unclear where else to publish some ideas.

Chapter 7 is a great addition to the book in terms of taking what went before and then providing authentication. However, in a previous chapter you showed people how to use Postman to test the API.

With the addition of authentication, however, that no longer works. Or, rather, you have to use Postman to authenticate as well by providing an authentication type. That would ideally be a good thing to have at the end of chapter 7 so that people can consistently understand how to interact with the API when there is authentication.

Just a thought.

How can I customize error raised from app.auth.authenticate(), my error handler is within .("libs/middlewares.js"),but this occurs after db.auth

Hi,
first of all, i really like your ebook! It's great!
But i got the same issue as has already been described here ( http://forum.casadocodigo.com.br/t/construindo-apis-rest-com-nodejs-consideracoes-durante-o-estudo/82 ) but my Portuguese is not so good ;).

I also attached my npm-debug.log.

Is it possible that you can explain some tips to solve this problem here?

I would be very grateful.

npm-debug.txt

I work with this fork: https://github.com/ArnaudValensi/node-express-sequelize-es2015

Your code also have same snipped, so i post issue here.

I ve got some bluebird warnings like "Warning: a promise was created in a handler at ... but none were returned from it" - for ex, code in auth.js:

const strategy = new Strategy(params, (payload, done) => {
    Users.findById(payload.id)
        .then(user => {
          if (user) {
            return done(null, { // << -- here is problem
              id: user.id,
              email: user.email,
            });
          }
          return done(null, false);
        })
        .catch(error => done(error, null));
  });

Here is explanation of problem in issue thread: petkaantonov/bluebird#508

Possible fix:

const strategy = new Strategy(params, (payload, done) => {
    Users.findById(payload.id)
        .then(user => {
          if (user) {
            return { // << -- fix 
              id: user.id,
              email: user.email,
            });
          }
          return false;
        })
        .asCallback(done)
        .catch(error => done(error, null));
  });

Big thanks for the book

but I'm currently getting a bug in the code. It is below
Unhandled rejection SequelizeDatabaseError: SQLITE_ERROR: table Tasks has no column named user_id
at Query.formatError (C:\Users\D-BELOVED\Desktop\ntask-api\node_modules\sequelize\lib\dialects\sqlite\query.js:348:14)

1. "before each" hook for "returns a list of tasks"

I have written the code exactly the same way it was in the book, literarily lifted it. Other tests are running except this particular ones.
and I have sqlite3 version 3.1.13 installed, couldn't install v 3.1.1 because it was always throwing error too

Thanks for your prompt reply

iam having following error when i hit /tasks URL

AfterContent Security Policy: The page’s settings blocked the loading of a resource at self (“default-src http://localhost:3000”)

Here is the console message:

at window.onload (:3001/js/app.js:875)

the attached file contains the ntask-web/public/js/app.js file the message is referring to:
app.zip

I have copied the files src/components/signin (and signup) and src/templates/signin (and signup) directly from the git hub source to eliminate that as a typo.

Any clues on where I should be looking?

Nice tutorial once again. Seems you missed the user_id column in the Task table. I tried to add it but still my test is still failing. Will keep on trying though

Running npm test deletes all data from the .sqlite file even though the test config sets a different db from the development config.

Can I please know where does app.db comes from?

app.db.sync().done(() => {
        app.listen(app.get('port'), ()=>{
            return console.log(`NTask API - Port ${app.get('port')}`);
        });
    });

Later, it got switched to app.db.sequelize.

app.db.sequelize.sync().done(() => {
        app.listen(app.get('port'), ()=>{
            return console.log(`NTask API - Port ${app.get('port')}`);
        });
    });

i'm not sure if i offered enough info or not, if you need more info to position the error , let me know, thank you very much.

Is it possible that you can explain some tips to solve this problem here?

Hello caio-ribeiro-pereira,

I am impressed the way the whole code and documentation is put together. It is easy to follow even for a beginner like me.

Kindly include the following in tutorial

1. Creating production build (If the api code is going to be deployed on customer end it should be obsfucated) and deployment (maybe using docker)
2. using process monitoring tool like PM2 (I tried but it does not work with the code)

I followed the steps laid out in the pdf and used passport js lib for authenticating the endpoints. However, I am stuck after I placed the app.auth.authenticate() in route.all() middleware. It's showing me ### Unauthorized as it should. How do I use the web token in Postman to view the tasks list? I am getting response from /token/ route, when I am providing a jsonified email and password. Not sure how to resolve this issue. When I remove app.auth.authenticate() I am able to see the task list (or create).

   app.route('/tasks')
	.all(app.auth.authenticate())
	.get((req, res)	=> {
		//Tasks: List tasks.
		Tasks.findAll({
			where: { user_id: req.user.id }
		}).then(
			result => res.json(result)
		).catch(error => {
			res.status(412).json({msg:error.message})
		});
	})
	.post((req, res) => {
		//Save Tasks: Save Task.
		req.body.user_id = req.user.id;
		Tasks.create(req.body).then(
			result => res.json(result)
		).catch(error => {
			res.status(412).json({msg:error.message})
		});
	});

I've gotten to the end of chapter 12 and tried to test it but have gotten hung up on this error. It is coming from the code that ends up in the browser, which is produced by babel, I assume, so I'm having a hard time identifying the source of it. It's hard enough troubleshooting my own code but code that's written by a machine is even harder. Here what I see in the Chrome debbugger:

window.onload = function () {
var main = document.querySelector("main");
new _app2.default(main).init();
};

The breakpoint is on the line "new _app2.default(main).init();" The browser is saying that _app2.default is not a constructor. Any ideas where I can look for the source of this error. I've checked all of my codes and it looks correct.

If you follow the book through to the end up chapter 8, the following test seems to always fail:

Routes: Token
    POST /token
        status 200
            1) returns authenticated user token

It always says:

Uncaught AssertionError: expected {} to contain key 'token'
  + expected - actual

  -[]
  +[
  +  "token"
  +]

That said, you get this by following the book code exactly. Checking out the current repo will not show that issue because it contains all changes. I've been doing a branch per chapter, which is how I'm able to isolate certain issues.

I am just curious, how does express instance is accessible inside routes directory?

module.exports = app =>{
    app.get('/', (req, res)=>{
        res.json({'status': 'NTask API'});
    });
};

app variable is defined in index.js file in root directory of the project but we use app in routes directory in both routes. Can you please explain this? Thanks in advance.

Hello everyone, i am a newbie. I'm following this tutorial and i have a problem as below.

/home/anh/Documents/nodejs/pilot/ntask-api/libs/middlewares.js:13
    app.use(app.auth.initialize());
                     ^

Can you tell me what i am missing? Thank you!

On page 7 under the section, What does NPM do?, you wrote: "+149 million downloads are made daily and +3.4 million downloads are made monthly."
Shouldn't 3.4 million i be 3.4 billion?

After cloning the repo, I try to run the app using:

$ npm start

And after doing that, I get the following dump:
