– that is all. git push
, and teams to manage staging and production by simply merging pull requests. Not only didNow 2.0 make deployments effortless, it made them scalable and global by default. Thanks to monorepo support, you could develop static websites andserverless lambdas within the same repository.
Today, we are excited to announce one command to run it all on localhost: now dev
.
Typically, developing a website or application involves a series of steps:
- Cloning repositories
- Fetching packages
- Synchronizing and matching ports
- Downloading the right runtime for each programming language
- And so on...
README.md
file for instructions about installing dependencies, and then tell a package manager to run developer scripts.
Now gives you a different contract. It is always now dev
.
When you work with servers, the developer workflow is quite tedious. You have to run a process, find the port, then make your changes, then kill the process (usually with Control+C)...
When you work with modern frontend frameworks (like Next.js or Gatsby) your HTML, CSS and client-side JavaScript, hot-reloading is expected instead.
now dev
ensures that every single request builds and runs the latest version of your code (yes, like .php
for every language). Every piece of technology, from the client to the Builders that compile your code into static files and lambda functions, is fully open-source and MIT licensed.
Now ensures that you write code with the same open and standard APIs of your programming language or framework of choice.
Whether it is Next.js pages, Node.js HTTP request handlers or Express.js endpoints – we ensure that your code remains agnostic and portable.
next dev
command (the old way of developing Next.js apps), now dev
allows you to run your entire suite of web apps and APIs all at once, with just a single command. now dev
: No matter how many builds, `now dev` will boot them all

script in package.json
... { "scripts": { "now-dev": "gatsby develop -p $PORT" } }
now.json
file that contains the@now/static-build Builder: { "version": 2, "builds": [{ "src": "package.json", "use": "@now/static-build", "config": { "distDir": "public" } }] }
gatsby develop
) is invoked automatically, along with all other Builders. The Gatsbygram example showcases this really well:
@now/static-build is the only Builder that requires adjustment to work with `now dev`
now dev
, you just run the command: In this example, both `@now/static` and `@now/go` are run in parallel
now dev
emulates production closely: As you can see, both `now dev` and `puppeteer` will boot up in no time
now dev
also acts as a substitute for serve
out of the box. Any time you want to serve a directory quickly, you know what to reach for: Even though there is no `now.json` file, serving the directory just works
now dev
is available in beta as part of the latest version ofNow CLI. To get it, run npm install -g now
or check out our otherdownload options. now init
: now init nextjs cd nextjs
and then...
