When I install jsonwebtoken on windows, I can easily require and use it. But when I install it on ubuntu using --save, not globallyI always face this error:. All I need to do is to copy this folder from windows to linux and it works. Can you provide the output of npm --version and node --version on Linux. It seems you may be using an old version of npm, and perhaps node. Node version 0. This project requires at least Node 4. Skip to content.

So what the heck is JWT or JSON Web Token?


JWT is a simple text string that can be used by the client and server to authenticate and transfer the information easily. A Token is encoded from a payload data using a secret key. That token is passed to the client. Whenever the client sends that token along with a request, the server validates it and sends back the response. Basically, JWT allows authentication without actually storing the user information on the system itself. Suppose a user tries to log in the application and on the successful authentication, the user will get a token in response. The token will look like this. A JWT Token mainly consists of three parts separated by. From the above JWT example, the header part is. From the above JWTM, the payload is —. Signature is generated by combining the first two parts of the Token with a secret key. The signature is used to verify that the sender of the JWT and to ensure that the message was not changed along the way. To create the signature, the Baseencoded header and payload are taken, along with a secret, and signed with the algorithm specified in the header. From the above JWT, the signature is —. The server verifies the token by creating the signature again. Signature is once again generated using the header and payload from the incoming JWT, and the secret key. Suppose someone tries to generate a fake token to access the sensitive data of a website. They can easily generate the Header and Payload but without knowing the secret key, they will not be able to generate signatures. There are many npm libraries available for implementing the JWT functionalities. Create an HTTP server with the essential routes in index. We have imported signIn, welcome, refresh method from the handler. I have created a config. In which I have declared the secret key for JWT and it expires time. It will take user credentials and log them. Normally we have a database for storing user information.

I can run npm install without issue, however, when I try to run mocha, I get the following:. Error: Cannot find module 'jsonwebtoken' at Function. I'm seeing lots of build issues for node projects. Especially with native modules, like this project. Hey codingchili. However, I cannot login. It keeps going back to the login page after I enter the credentials and token code. How did you solve the first issue? Anything in the logs? Could you check network requests in your browser? I've been using the RP for quite a while without issue using nginx basic authjust wanted to test this plugin. Also - maybe you should add a note to the readme. I installed x-pack and then applied a free license. I had to comment out the routes that the x-pack plugin creates before getting to this point. Have not seen this issue before, but I have also not used either x-pack nor a reverse proxy with kibana. Skip to content.

Node.js + MongoDB: User Authentication & Authorization with JWT


Related Posts: — Node. Together they are combined to a standard structure: header. We need to install necessary modules: expresscorsbody-parsersequelizemysql2jsonwebtoken and bcryptjs. Run the command:. In the app folder, create config folder for configuration with db. First five parameters are for MySQL connection. In models folder, create User and Role data model as following code:. We use User. In development, you may need to drop existing tables and re-sync database. So you can use force: true as code above. For production, just insert these rows manually and use sync without parameters to avoid dropping data:. To verify a Signup action, we need 2 functions: — check if username or email is duplicate or not — check if roles in the request is existed or not. We get token from x-access-token of HTTP headers, then use jsonwebtoken 's verify function. There are 2 main functions for Authentication: - signup : create new User in database role is user if not specifying role - signin :. Now, do you have any question? Would you like to know how we can combine middlewares with controller functions? Let's do it in the next section. We can separate our routes into 2 part: for Authentication and for Authorization accessing protected resources. If you check the database, you can see things like this:. Today we've learned so many interesting things about Node. Despite we wrote a lot of code, I hope you will understand the overall architecture of the application, and apply it in your project at ease. If you need a working front-end for this back-end, you can find Client App in the post: - Vue. You can find the complete source code for this tutorial on Github. Just one question, can we integrate this with sequelize migrate due to the fact that it makes the job easier for entitites. Yes, we can. Great walkthrough! Helped a lot. I like the way that you organize the models, controllers and routes in every tutorial. Great Tutorial, thank you very much! Everything is working and I am trying to build a page where an admin can change the User Roles of a specific user. Right now, I have no Idea what to change or how I would implement this on the backend site.

nodejs中使用jsonwebtoken模块遇到的错误

As I understand with the last update on May 9, lib integrated with 'passport-jwt' which use 'jsonwebtoken' inside. So, for now, 'jsonwebtoken' exist only in devDependencies package. If you see, passport today is also a devDependency, and you're only pointing out that the issue is on the jsonwebtoken one. If your app is going to be using passport, your app is probably defining it as dependency vs devDependency. The same should be with jsonwebtoken. I think the fix here is not to move it to the dependencies block, as this library doesn't make use of it at all. Fix is probably relying on documenting the use of the integration, and saying that if you're going to use it on a passport enabled app you'll need to add as well the jsonwebtoken dependency in the dependencies block. The problem with your index. Meaning that all require's have to be resolved, no matter what I use, or what I do not use in my app. If you really want to make the passport integration optional, then instead of require'ing it during initialization, let the user call a function to require it. IMO the passport integration should be optional. Not everyone will like adding jsonwebtoken as a dependency of their app just to skip this "require error" if they are not going use it at all. Then the fix can be checking if the passport module is present and only then require that integration file, which will of course require the jwt library as well. That's something we can document. I'm wondering right now about having a stable package. What we spect as users of the library is to install it and use it with any problem. So, even though you want to add this to the documentation, in order to offer a good developer experience and avoid breaking many applicationsI'd prefer and I really to resolve all the needed dependencies under the installation. We know that the passport integration should be optional; in this case, some solutions can be taken into account; for now, I can think of:. But the most crucial part today is to release a usable version of the package and avoid breaking more applications. There is already a PR with a quick fix 89which is even faster than adding a section into the documentation. Does this sound reasonable? The "quick fix" in 89 may solve it for you but may bring issues for other people.
