This repository has been archived by the owner. It is now read-only. Star Copy link. After updating to version 2. I am also having this issue, hope to see a solution soon. This started happening. Zend throws Exception after Update but I did not change anything. The short-term fix is to pin to zend-serializer 2.
The update fixed it! If you receive the response as pong, it means that your server is just working fine.
We can now proceed with further implementations. We might now need to set up our server post and add event listeners since we are working with node. To do that, we need to initialize the boilerplate for our application. Use the below code snippet as a reference. Now, we might use any external API for our application.
A sample API request might look something like this. Now, we need to define the external routes from the API that would receive data and send them back to the client.
This is how it is done. Now, the next and the main task that we are here to achieve is to establish cashing. It can be done by establishing the connection of our application to the Redis server. It can be done if we have installed the Redis package earlier.
The code is shown below:. We are almost done now. The last task now is to compare the received data from the cache. To check if the data is present or is null is done by using the example code snippet shown below. In the above code snippet, to get data from the external API, we need to first store it in the Redis and is then sent it to the node server so that it can respond with data and not just making a request from the API.
The setex function is used to store data in the cache. Using this function alone instead of a generic regular function may not allow us to set the time. Thus, there's an advantage of using this function to set time in the form of key-value pairs. The set value of specified time will alert Redis and it would automatically remove the key-value pair from the cache when the time interval elapses or expires.
In this tutorial, we have covered almost all the prospects of Redis and the caching mechanism. The primary aim of this tutorial is to discuss the Redis cache from scratch.
We came across what is Redis and how caching is achieved through it. We have also taken into account some coding examples and how to determine if the caching data already exists or is NULL. We finally came across the error message displaying a method that responds as an error from the external API if there's no data present or it simply doesn't exist. JavaTpoint offers too many high quality services.
If "always" then always shows colors. If true, then only prints color codes for tty file descriptors. Run git commit hooks when using the npm version command. The depth to go when recursing packages for npm ls. If not set, npm ls will show only the immediate dependencies of the root project. If --all is set, then npm will show all dependencies by default. Show the description in npm search. Define arguments to compare in npm diff. Destination prefix to be used in npm diff output. Ignore whitespace when comparing lines in npm diff.
Prints only filenames when using npm diff. Do not show any source or destination prefix in npm diff output. Note: this causes npm diff to ignore the --diff-src-prefix and --diff-dst-prefix configs.
Source prefix to be used in npm diff output. Treat all files as text in npm diff. The number of lines of context to print in npm diff. Indicates that you don't want npm to make any changes and that it should only report what it would have done. This can be passed into any of the commands that modify your local installation, eg, install , update , dedupe , uninstall , as well as pack and publish.
Note: This is NOT honored by other network related commands, eg dist-tags , owner , etc. The command to run for npm edit and npm config edit. If set to true, then npm will stubbornly refuse to install or even consider installing any package that claims to not be compatible with the current Node. This can be overridden by setting the --force flag. The "retries" config for the retry module to use when fetching packages from the registry. The "factor" config for the retry module to use when fetching packages.
The "maxTimeout" config for the retry module to use when fetching packages. The "minTimeout" config for the retry module to use when fetching packages. The maximum amount of time to wait for HTTP requests to complete.
Removes various protections against unfortunate side effects, common mistakes, unnecessary performance degradation, and malicious input. If you don't have a clear idea of what you want to do, it is strongly recommended that you do not use this option! Run all build scripts ie, preinstall , install , and postinstall scripts for installed packages in the foreground process, sharing standard input, output, and error with the main npm process.
Note that this will generally make installs run slower, and be much noisier, but can be useful for debugging. Format package-lock. When "true" displays the message at the end of each npm install acknowledging the number of dependencies looking for funding. See npm fund for details. The command to use for git commands. If git is installed on the computer, but is not in the PATH , then set this to the full path to the git binary. Tag the commit when using the npm version command.
Operates in "global" mode, so that packages are installed into the prefix folder instead of the current working directory. See folders for more on the differences in behavior. This obviously will eliminate some deduping.
If used with legacy-bundling , legacy-bundling will be preferred. The config file to read for global config options. The string that starts all the debugging log output. A proxy to use for outgoing https requests. If true, npm will not exit with an error code when run-script is invoked for a script that isn't defined in the scripts section of package. This option can be used when it's desirable to optionally run a script when it's present and fail if the script fails. This is useful, for example, when running scripts that may only apply for some builds in an otherwise generic CI setup.
If true, npm does not run scripts specified in package. Note that commands explicitly intended to run a particular script, such as npm start , npm stop , npm restart , npm test , and npm run-script will still run their intended script if ignore-scripts is set, but they will not run any pre- or post-scripts. Option that allows for defining which types of dependencies to install. This is experimental, and not implemented by the npm public registry. The value npm init should use by default for the package author's email.
The value npm init should use by default for the package author's name. The value npm init should use by default for the package author's homepage.
The value npm init should use by default for the package license. A module that will be loaded by the npm init command. See the documentation for the init-package-json module for more information, or npm init. The value that npm init should use by default for the package version number, if not already set in package.
Whether or not to output JSON data, rather than the normal output. A client key to pass when accessing the registry. It is not the path to a key file and there is no "keyfile" option. Causes npm to install the package such that versions of npm prior to 1. This eliminates all automatic deduping. If used with global-style this option will be preferred.
Causes npm to completely ignore peerDependencies when building a package tree, as in npm versions 3 through 6. If a package cannot be installed because of overly strict peerDependencies that collide, it provides a way to move forward resolving the situation. Use of legacy-peer-deps is not recommended, as it will not enforce the peerDependencies contract that meta-dependencies may rely on.
Used with npm ls , limiting output to only those packages that are linked. The IP address of the local interface to use when making connections to the npm registry. Must be IPv4 in versions of Node prior to 0. When passed to npm config this refers to which config file to use. What level of logs to report. On failure, all logs are written to npm-debug. Any logs of a higher level than the setting are shown.
The default is "notice". See also the foreground-scripts config. Show extended information in ls , search , and help-search. Commit message which is used by npm version when creating version commit. Options to pass through to Node. This does not impact how npm itself is executed but it does impact how lifecycle scripts are called.
