So the real first step from there is to install the Nest CLI and to open a new project. The only real prerequisite is Node.js, as TypeScript comes packaged with the Nest installation. The types of modules – marked by the decorator – will be one of these four properties: imports, exports, controllers, or providers.Ĭustom modules, once built, are imported to the root AppModule via the file. That is supposed to make it easily scalable, maintainable, testable, and “loosely coupled.” The core element of that architecture is the module, which every Nest.js app is broken into by default. Nest has “out-of-the-box” or ready app architecture that it says is highly modeled off of Angular. Simultaneously, it serves as an abstraction layer on top of Express. It is built with – and has in mind – TypeScript at its core while supporting basic JS. Its main reason for being: application architecture. Nest.js = TypeScript + Node.js (+ other stuff)Įventually we reach Nest, an increasingly popular “progressive” Node.js framework. Node users have a few options for frameworks, but one of the more popular ones is Express.js. Node scales using a single-threaded connection instead of weaving a new thread for every new connection.
You can also read more about debugging Node.js. Node is lightweight, so is built for speed and agility – it’s got high throughput while allowing a high number of simultaneous two-way connections. Ryan Dahl created Node.js with the goal of giving JS (or the websites it constituted) push capability: two-way communication instead of everything depending on the client. Node.js is a JavaScript runtime, over a decade old at the time of writing (not to assume a 2022 tutorial’s longevity into the 2030s, but I’m an optimist). There’s no difference between “vanilla” and “French vanilla,” I just needed to add some flavor to this so I spruced up the h3 here. Without supersets like TypeScript, JavaScript wouldn’t have survived in the cloud-native and microservices era.

You can check large-scale code projects more quickly. With use cases like debugging in particular, type-checking speeds up. The extra features do heavy lifting for larger JS projects, primarily by being more specific in code (e.g., explicitly id’ing types of JS variables, hence the name). TypeScript is an evolved, object-oriented superset of JS. Sketching the Nest.js Architecture: JS, TypeScript, Node & Express JavaScript vs. Nest combines a number of developments in the world of JavaScript and positions sees itself filling in the role of providing scalable server-side development (versus frontend). Nest.js calls itself a progressive Node.js framework (note Vue.js also defines itself that way). But this is where the distinctions become important – understanding the role of a progressive framework like Nest.js and how we got here. But knowing the original or primary intent of a tool like React.js (it’s a library), can make it easier to grasp how it works and with which other JS tools. The differences seem pretty trivial, as a lot of tools seem to work in both limited and expanded capacities.
There can be confusion out there given the size of the JS ecosystem.
