![]() ![]() To support a monorepo structure, Appflow needs a singular file at the root of the monorepo repository. Serve one of the applications ( lerna run start -scope=), change your dark mode preference, and refresh the browser to test it out! Integrating with AppflowĪppflow is Ionic’s mobile CI/CD platform that makes it easy to build, publish, and update your apps over time. Update lerna.json so we can relay our monorepo’s structure to Lerna: from In App.tsx, wrap the component and it’s children with, so is the outermost component of the App template. We can modify what folder(s) house our packages - let’s create a folder to house our Ionic Framework React applications, and another to house our shared React libraries. By default, Lerna declares that all of your monorepos packages will be housed in the packages/ folder. $ git init my-organization & cd my-organizationĬrack open the generated lerna.json file. This space will hold all of our packages and is committed to source control as one repository. Our monorepo will consist of three packages (monorepo speak for subprojects) two Ionic Framework React applications, and a shared React library that will supply a React context each application will use.īefore we start generating Ionic Framework applications or building the shared code library, we need to initialize a Lerna repository. I personally like how lightweight it is, and it works well with Ionic Framework React projects and Ionic Appflow. In this blog post we’ll be building out a monorepo using Lerna. In fact, we use monorepos here at Ionic! Several monorepo tools are available to development teams: Nx, Yarn workspaces, npm workspaces, Lerna, Turborepo…and I’m sure more that I’m not even aware of. With solutions to those problems, it’s not shocking to see that monorepos are rapidly growing in popularity. ![]() How do you share common bits of code between projects? How do you sync dependencies across projects? How do you optimize collaboration between projects? ![]() By the end of the series, you’ll have the tools you need to adopt monorepo setups in your organization.īuilding and maintaining multiple development projects comes with a unique set of problems teams need to solve. Coordinating several changing version numbers is hard, and that's what lerna is designed for.This is part one of a new series on monorepos. In short, they put symlinks inside node_modules, so when you modify a package, the dependent packages can see it.īut there's another problem: when a package A depends on a package B that increases its version number (because it's modified), then package A should change the version number, too. But - surprise! - it has its drawbacks.Īt development time, you have to keep up to date the dependencies of each module with each other in order to "see" the changes. Splitting the code into small modules is a great way to write clean, decoupled, high quality and well-tested code. Use yarn workspaces if you're building something with several packages (like a big application) but, if you intend to publish that packages into a registry (like a library or a framework) use lerna instead. I've recommended yarn workspaces over Lerna in the past, but now I want to be more specific about why. The other day, one of our developers messaged me on Slack about a tool called Lerna.
