check-update | Check if there is an update

I am install any Cordova plugin after run ionic serve that time show error

[error] Error: The target entry-point "@ionic-native/device" has missing dependencies:

• @ionic-native/core

[ng] An unhandled exception occurred: The target entry-point "@ionic-native/device" has missing dependencies: [ng] - @ionic-native/core [ng] See "C:\Users\abc\AppData\Local\Temp\ng-LALJIx\angular-errors.log" for further details.

I'm receiving the below error when trying to deploy the below Ansible script. It is related to the copying of the yum output to a .txt file and does seem to be something trivial with the syntax. Any help decoding the error would be much appreciated.

I am trying to put together my first React Typescript JSX component npm package.

I copied working code from a CRA TypeScript project to an empty folder and added the following package.json and tsconfig.json.

We have an active version of our app which starts polling the server right away to get some basic info - when the request fails, it retries after a second until the request succeeds.

In the newer version, we have removed this polling: i.e. the old endpoint does not exist anymore.
The problem now is, that the PWA never updates to the newer version: i.e. when a user, who has already opened the old version before, opens the app, they will see the old version that constantly tries to poll the server (and this request fails of course). But the angular service worker never updates to the new version (i.e. refresh does not work, closing the browser tabs, or the whole browser does also not work).

Note: The issue seems to be related to the polling

• When we have an app version that polls the server successfully (i.e. polling stops), the app will be updated as expected
• When we have an app version that does not poll the server, the app will be updated as expected
• But in our case, we have an app that polls the server and polling constantly fails (and will be retried every second): In this case, the app is never updated!

The only workaround is to press CTRL+F5 to hard-reload the app.
But this is of course not a solution because average users don't know that they can/should do this...

Any idea how to solve this issue?

• We need a solution that can be done on the server: i.e. it's not possible to tell every user to press CTRL+F5 or uninstall the app via dev-tools, etc.
• A temporary nasty workaround for now is that we reimplemented the endpoint (that the old versions poll) and return some valid dummy data

Here is a test-app to reproduce the issue: https://github.com/tmtron/pwa-test
The readme file contains full details.

Initial state:

We have started the app before and the browser has the version of the PWA that constantly polls the server and fails. Now we close the browser tabs (that show our app)

• Next: build and serve a new app version
• When we open the browser it will still serve the previous app-version 2 (as expected)
• since this is a navigation request the browser will check for updates
• when we watch the terminal of the http-server - after some seconds it will show that the browser requests a new version of the ngsw-worker.js ...

I'd like to install tcmalloc from source.

I'm on centos8. I'd install from yum but don't see any google-perf or gperf or anything of the sort available. (I did do yum check-update.)

The instructions on the tcmalloc github sure are simple. Install bazel (check). Then run bazel test //tcmalloc/... in the /tcmalloc dir. Then, it claims, "Congratulations! You've installed TCMalloc"!

Ok tcmalloc team, love you guys, but... I think our definitions of install are different. I don't see any bit of libtcmalloc available in /usr/lib/ or /usr/lib64/ or anywhere else for that matter.

How do I get a nice, plain, old shared library outputted by this bazel beast? Linking in via bazel to my project as described is not an option.

I have a react app with deprecated dependencies. To make it work, I have to update the dependencies to their newer (but stable) versions.

As per this stakoverflow thread, to update dependencies in package.json to latest versions, npm-check-updates is the Best Option. However, I'm using yarn for package management. Is there an equivalent of npm-check-updates in yarn. So that, I use a single package manager to manage my dependencies.

I want to check if updates are available, and if so, perform some steps before I install the updates. I run yum check-updates to see a list of updates available for installed packages, but I'd like to grep this and get a count that I can use for some logic in a bash script. So ideally, I would like to grep that output of check-updates and return 0 if there are no updates, or if five updates are available then I would like the grep to return 5.

How can I grep this to return the count?

On my local machine, npm run build works just fine. On my Docker image launched via Jenkins, I get issues like
