            NX NestJS Angular, Why is Ivy complaining about modules that are not part of the frontend app?
            Asked 2021-Apr-11 at 02:37

            Hello my fellow developers!

            So I've been working on this app for a while now. I like to be up to date with the frameworks I use, so I regularly update when the frameworks release a new version. i.e. Angular 9 > 10. Angular 10 > 11.

            So I just recently updated to Angular 11 and updated my nestjs and nx. And now when I try to serve my frontend app, Ivy seems to complain a lot.. but a.. lot... about modules that are not used in the frontend app.

            After a day's review of the project, I was:

            • importing a class from the middleware that was using a library of the backend.

            • using a library from the backend in the frontend

            To fix the issues also complies with best-practices.

            I have split the class in the middleware into two classes: one for the frontend, one for the backend. I have refactored the code so that the backend library was not necessary on the frontend. I ended up just fixing two files. And all the errors dissapeared.

            So if you encounter something similar, double check whether or not you use some backend libraries/classes in your frontend.

            Explanation, "this" syntax JavaScript
            Asked 2021-Feb-17 at 02:04

            So I was making a node app that had a conditional statement in the class constructor, if this then variable is equal to that, else variable equal to that. However, when I initialize that variable I want to change depending on the boolean statement with "this" syntax it gives me an error in the console. Why does this happen? And how can I initialize that variable if I can't initialize it more than once with "this" syntax in JS?

            Update:

            I was given How does 'this' work in JavaScript? to see if this helps, and it has nothing to do with what I asked. To be more specific, it's like why can I do this var test; if(true){var test = 1}else{var test = 0} and not this if(true){this.test = 1}else{this.test = 0} and be able to use the variable all throughout my app.

            Verify and decode Cognito JWT in nodejs with smallest code footprint
            Asked 2021-Feb-05 at 09:46

            I have an application that runs as AWS Lambda function using Cognito authentication. It all works fine but now I am attempting to optimise the bundle size to reduce cold start times.

            The process of verifying and decoding the JWT involves:

            • Fetch JWK from internal AWS endpoint
            • Call jwkToPem from jwk-to-pem module
            • Verify and decode JWT using jsonwebtoken module

            ANSWER

            Answered 2021-Feb-05 at 09:46

            Given that the "Fetch JWK from internal AWS endpoint" step is fetching from a JSON Web Key Set, the jose version 3.x module can do everything for you.

            The disk size is bigger, but that's because it's a universal module and bundles runtime also for the web, in both esm and cjs flavours, but don't fret - in your runtime it requires only the node runtime files and has 0 dependencies. And you can use rollup to tree-shake all of the weight you're not using (other submodules and runtime files).

            How to force WebPack to use one version of module (instead of 6 different versions?)
            Asked 2020-Oct-29 at 09:13

            In our project Webpack-bundle-analyzer plugin says that the bundle uses specific module (js file) 6 times.

            What is the best way to make project as it used only one ( instead of multiple)? I know they might be from dependencies' depencendies, but how such problem should be solved?

            I am OK with checking my APP manually for possible code-breaks, but the goal is surely to use one bn.js. Our package.json doesnt contain it in any dependencies directly.

            ANSWER

            Answered 2020-Oct-29 at 09:13

            This situation happens probably because your app (or it's dependencies) are requiring a different version of the same lib.

            It is not recommended to "force" the same version by hacking some Webpack's config (it is possible). There is a meaning to semantic versioning, if the lib bumped a major version, this means that it contains breaking changes.

            A better approach will be to manually align the version of the lib (or its consumer).

            You can run yarn why lib-name or npm ls lib-name which will print you a list of dependencies which are consuming the lib and at which version, this will help you to upgrade the dependencies in order to align the versions.

            If you still want to force, you can check these solutions https://github.com/webpack/webpack/issues/6505

            1. Using yarn resolutions to install only one version.
            2. Using webpack alias, to alias the lib-name to a specific path (each different version is installed in the consumer node_modules folder)
            3. Force webpack to resolve only from the app node_modules by

            As we mentioned to you in your helpdesk ticket on this same topic, our deploy environment is very naked - you have to:

            1. specify dependencies that we can automatically install - npm/yarn deps, bower deps, gems and python packages.
            2. install other dependencies yourself. the 'dotnet' program will be one of this type. We don't have it in our install environment, so you need to somehow import a copy of it into the environment. Seems like you can download the entire SDK here: https://www.microsoft.com/net/download/linux and then you need to import ONLY what is necessary for your build - it will take a very long time to build your site if we have to download the entire SDK, so see what you can trim down to get 'dotnet' to run.

            For the purposes of #2, you'll probably need to test things in our build environment. How to do that, and details you'll need about the build environment such as OS type so you can download the right version of the SDK are described in this article:

            https://www.netlify.com/blog/2016/10/18/how-our-build-bots-build-sites/

            This will take some work on your part. It will not be trivial. It is not something we can help with in more detail than that for free customers unless you come with specific questions and examples.

            To address some thoughts in the comments:

            • build.sh is indeed our build script
            • 9:46:52 AM: /opt/build/build.sh: line 427: dotnet: command not found means that literally there is no dotnet command available to run - not that some config file is missing.
            • we only try to run it once since you have set your command to use && to chain several commands - one fails, the whole chain fails, and we don't need to run it two more times once the first failure occurs :)
