This hash in the file name enables long term caching techniques. When running a production build of freshly created Create React App application, there are a number of.

If the contents of a file changes in a subsequent build, the filename hash that is generated will be different. To deliver the best performance to your users, it's best practice to specify a Cache-Control header for index.

This header allows you to control the length of time that the browser as well as CDNs will cache your static assets. If you aren't familiar with what Cache-Control does, see this article for a great introduction. ReactDOM automatically supports profiling in development mode for v You can opt-in by using the --profile flag.

Use npm run build -- --profile or yarn build --profile to enable profiling in the production build. See the React docs for details about profiling using the React DevTools. Docs Help GitHub. Create React App. One of the potential advantages with splitting your vendor and application code is to enable long term caching techniques to improve application loading performance.

Since vendor code tends to change less often than the actual application code, the browser will be able to cache them separately, and won't re-download them each time the app code changes.

Install the build tools with this one-liner.

Start PowerShell as Administrator and run:. These tools are required to compile popular native modules. If not already installed, it will also install Python 2. NET Framework 4. If you see anything that indicates otherwise, please file a bug. This module is capable of installing either the build tools from Visual Studio or Visual Studio By default, this tool will install the build tools. To change that, run this script with the --vs parameter.

This tool does not check if the parameters make sense - passing incorrect parameters might break the whole installation. Supply parameters to windows-build-tools as a JSON array. Here's quick example note the double quotes :. If you run windows-build-tools with --vsthese parameters are available:. The available parameters are documented here. By default, windows-build-tools will download the latest installers from Microsoft each time it's installed.

Alternatively, you can prepare a folder that contains installers. They need to have their original names:. This package currently only handles the most common use case, none of the edge cases.

If you encounter errors, we'd greatly appreciate error reports and even pull requests. This is currently tested on Windows However, thanks to brucejo75, the following steps can be taken to install to a different user account:. Ensure that the variables passed match your location of npm's roaming data and the location of user profiles on your machine.

For more information, see the npm config set prefix description here. To ensure that that's true, we take a fresh Windows 10 installation, add windows-build-toolsand ensure that the most popular native Node addons compile from source.

Npm scripts are defined in your package. If you use a build tool Grunt, Gulp, Webpack etc.

npm build production command

Most plugins for build tools simply wrap the underlying package that usually has a CLI. A simple solution to these problems would be to remove the sometimes complex abstraction of build tools altogether and run the underlying packages manually on the command-line.

Angular CLI: Serving and Building for Production

This is a great solution, but how are you going to remember all of those CLI commands and their options? And how are you going to chain them together? Enter npm scripts. Npm has a run command that can run scripts defined in the scripts property of a package. First we need to install it:. Note that the --save-dev flag saves this package in the devDependencies section of the package.

This makes it easy for other developers to install the required packages in the future by simply running npm install. Now try running npm run scss. Hopefully, you should see your Sass file successfully compiled to CSS and the command output should be the same as running node-sass manually.

This process can then be repeated for the rest of the requirements for our project. Another important thing to note is that, because npm run is itself a CLI command, it can be run from other scripts to chain scripts together. For example:.

What is Exactly? - a beginners introduction to Nodejs

We can do so by creating a new concat script that runs both npm run Once we have all of our required packages installed, the devDependencies section of our package.

Splitting things into logical groups not only makes it easy to chain scripts together, but also helps when you might only want to compile a certain group of your assets.

For example, watching for changes. Being able to compile all of your front-end assets using a single npm run build command is useful, but it will quickly get annoying if you need to run it after every time you change part of your code.

We can achieve this by using a package like onchange. First, install it by running:. The onchange command works by watching files you specify using a glob pattern, then running a command you specify after Create React App is an officially supported way to create single-page React applications. It offers a modern build setup with no configuration. If you've previously installed create-react-app globally via npm install -g create-react-appwe recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version.

They are preconfigured and hidden so that you can focus on the code. You can now optionally start a new app from a template by appending --template [template-name] to the creation command.

Templates are always named in the format cra-template-[template-name]however you only need to provide the [template-name] to the creation command. Our Custom Templates documentation describes how you can build your own template. You can start a new TypeScript app using templates. To use our provided TypeScript template, append --template typescript to the creation command. If you already have a project and would like to add TypeScript, see our Adding TypeScript documentation.

When you create a new app, the CLI will use Yarn to install dependencies when available. If you have Yarn installed, but would prefer to use npm, you can append --use-npm to the creation command. For example:. Running any of these commands will create a directory called my-app inside the current folder. Inside that directory, it will generate the initial project structure and install the transitive dependencies:. No configuration or complicated folder structures, only the files you need to build your app.

Once the installation is done, you can open your project folder:. Runs the app in development mode. The page will automatically reload if you make changes to the code. You will see the build errors and lint warnings in the console. Runs the test watcher in an interactive mode. By default, runs tests related to files changed since the last commit.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Getting Started

I've used this template which worked great locally - kudos for that - but after building and including the dist folder in a repository the router never starts the app and there's no console error either. You don't have vue-router installed, so it shouldn't work in development or production right now. In the future though, since the problem is specific to your code and does not affect a freshly generated project using this template, either the forum or the Gitter chat would be a better place for questions like this.

Thanks for checking that chrisvfritzI did install it but somehow didn't got to the dependencies inside the package. It's weird the fact that it works on my computer, it still doesn't on the gh-pages address.

I will move this to the forum. Thank you. It doesn't look like you've rerun npm run build and commited the new dist after adding vue-router to dependencies. After that, you may also need to do a hard refresh as this template doesn't add asset hashes like the more complex Webpack template. I did rerun build. Any idea on how to do that hard refresh?

I mean, what is that I should manually do to actually reflect that change? There isn't anything more that should need to be done to reflect a change. I unfortunately don't have time to take a deep dive into why your application might not be working, but I can leave you with this last thing I noticed at a quick glance. The activate and deactivate hooks on your search page should theoretically never resolve, since they take a transition argument and one needs to call transition.

See the vue-router docs for more. Hope this helps and that you're able to get your app working! It's ok chrisvfritzdidn't expect anyone to waste their time with this specific debugging, it wouldn't feel right. I thank you for taking some of your time to take a quick look at it. Since it's not throwing an error, my assumption is that the root view is not showing because of the path on the location of my GitHub page and it explains why locally it works on both dev and production mode.

The final test would be to put that solution in a server and see what happens. Can you explain with an example? Some months had passed, I don't remember very well the thread Skip to content.

To deploy, instead of running nuxtyou probably want to build ahead of time. Therefore, building and starting are separate commands:. You can also set server. Unix sockets are also available if you set the server. When using Unix socketsmake sure not to set the host and port parameters otherwise the socket parameter is ignored.

Note: we recommend putting. It will create a dist folder with everything inside ready to be deployed on a static hosting site.

If you have a project with dynamic routestake a look at the generate configuration to tell Nuxt. When generating your web application with nuxt generatethe context given to asyncData and fetch will not have req and res.

The content is generated at build time. For example, we can't use it for applications where content depends on user authentication or a real time API at least for the first load. The SPA idea is simple! When SPA mode is enabled using mode: 'spa' or --spa flag, and we run build, generation automatically starts after the build. This generation contains common meta and resource links, but not page content.

Another possible deployment method is to use Nuxt as a middleware in frameworks while in spa mode. This helps reduce server load and uses Nuxt in projects where SSR is not possible.

In this guide, we'll dive into some of the best practices and utilities for building a production site or application. This walkthrough stems from Tree Shaking and Development.

The goals of development and production builds differ greatly. In developmentwe want strong source mapping and a localhost server with live reloading or hot module replacement. In productionour goals shift to a focus on minified bundles, lighter weight source maps, and optimized assets to improve load time. With this logical separation at hand, we typically recommend writing separate webpack configurations for each environment.

While we will separate the production and development specific bits out, note that we'll still maintain a "common" configuration to keep things DRY. In order to merge these configurations together, we'll use a utility called webpack-merge. With the "common" configuration in place, we won't have to duplicate code within the environment-specific configurations.

Let's start by installing webpack-merge and splitting out the bits we've already worked on in previous guides:. In webpack. Also, we've added the recommended devtool for that environment strong source mappingas well as our simple devServer configuration. Finally, in webpack. Note the use of merge calls in the environment-specific configurations to include our common configuration in webpack. The webpack-merge tool offers a variety of advanced features for merging but for our use case we won't need any of that.

Now, let's modify our npm scripts to use the new configuration files. For the start script, which runs webpack-dev-serverwe will use webpack. Feel free to run those scripts and see how the output changes as we continue adding to our production configuration. Many libraries will key off the process. For example, when process. However, with process. Since webpack v4, specifying mode automatically configures DefinePlugin for you:. It is used by convention to determine dev-vs-prod behavior by server tools, build scripts, and client-side libraries.

Contrary to expectations, process. Thus, conditionals like process. If you're using a library like reactyou should actually see a significant drop in bundle size after adding DefinePlugin.
