:one: What are the main similarities between the two?

Both npm and cargo are used by developers to install dependencies into their projects, providing additional utility or convencience to the developer. Instead of having to build large libraries, a developer can install a package and use the pre-written functionality.

:two: Are there any significant differences?

Cargo and npm are mostly the same, however cargo is a test/benchmark runner and also has a number of features out of the box which don’t exist with npm; for example workspaces. Workspaces are created where one or more packages share dependencies.

Cargo also has dependency overrides.

:three: What is the equivalent of cargo new in the npm world?

In npm, a developer will use the command npm init project-name to create a new node project, as cargo new project-name would be used with cargo.

:four: What is the equivalent of package.json in the cargo world?

In cargo, the Cargo.toml file represents the packages tracks some of the project metadata and holds the details of the packages, much like package.json does for npm

:five: What is the equivalent of cargo run in the npm world?

The command cargo run will build and execute the target file which is output from the cargo build command.
This is similar to npm run build, npm run prod, npm run dev or npm run start depending on whether the developer wishes to have hot module reloading and efficiently built project.
The closest comparison would be between cargo run and npm run build and then npm run prod.

  1. What are the main similarities between the two?
    Cargo is Rust’s package manager, similarly to npm, the package manager for JavaScript.

  2. Are there any significant differences?
    They are developed for different programming languages (Cargo for Rust, npm for JavaScript). Cargo also has builtin support for common tasks like running code, building code etc. Cargo has features like workspaces (similar to lerna), dependency overrides (similar to patch-package) out of the box. It is also a test runner (similar to mocha, jest etc), benchmark runner etc.

  3. What is the equivalent of cargo new in the npm world?
    npm init

  4. What is the equivalent of package.json in the cargo world?
    cargo.toml

  5. What is the equivalent of cargo run in the npm world?
    npm run start

  1. What are the main similarities between the two?
  • Both cargo and npm are package managers which is used to simplify the management of package dependencies.
  1. Are there any significant differences?
  • In simple term, cargo is built for Rust programming language. Whereas, npm is built for javascript.
  1. What is the equivalent of cargo new in the npm world?
  • npm init project-name
  1. What is the equivalent of package.json in the cargo world?
  • Cargo.toml
  1. What is the equivalent of cargo run in the npm world?
  • Since cargo run both builds and runs the project. I’d say the closest code equivalent in npm world is npm run build & npm run prod

  1. Both manage libraries of packages And create manifest/dependencies of packagese so other developer can download all the packages used in our project.

  2. Besides being the package & dependencies manager of rust, Cargo is also a building tool/test runner/project bootstraper.

  3. npm init -y

  4. cargo.toml

  5. npm build and then npm run-script

While each manage Libraries of packages for building and running a project, the primary difference is Cargo’s ability to both build and run code far more efficiently than JS Node while automating the NPM run, build and NPM run.prod commands. This is across the complete code base as well including within core functions like test, extension, Function creation, tool management as well as cross platform run extensions for Windows.exe, MacOS and JS Frameworks. The dependency manager with runtime automation is super cool! Instantly loving this at first blush, but let’s see how it fares upon more complex runtime builds.

NPM is for Node.js and cargo is designed to efficiently execute Rust code

npm init.
cargo.toml

Research the Internet and learn a bit about both Cargo and the Node Package Manager (npm).
What are the main similarities between the two?

Both have manifest file that constructs list for the packages to be mounted/imported. Both have very similar architecture, have identity initializer and dependency packages list.

Are there any significant differences?

Manifest file types in npm is JavaScript, in cargo is TOML.

What is the equivalent of cargo new in the npm world?

$ npm init

cargo.toml

What is the equivalent of cargo run in the npm world?

cargo run initializes development phase for the project like in npm run start

  1. Npm and Cargo share all basic command (with their semantic differences).
  2. Cargo have additional-tool as : cargo-edit (If you skimmed the above portion,and to help manage dependencies on the command line),
    cargo workspaces (or cargo ws)(simplifies creating and managing workspaces and their members.)

1. What are the main similarities between the two?
  • Both are package managers that use config files to store dependencies
  • Have similar CLI commands like init, install / add
  • Can install locally or globally
2. Are there any significant differences?
  • Cargo config file use TOML where npm uses JSON
  • Cargo handles the common tasks by default like cargo run, cargo build but does not have a built in task runner like npm for custom defined tasks
  • Can make up for some of the differences by installing packages like cargo-edit
3. What is the equivalent of cargo new in the npm world?
npm init
git init --yes

Would also need to manually add the .gitignore. The cargo new command is more like npx create-react-app in that it generates a new project template with the standard directory structure and git already set up.

4. What is the equivalent of package.json in the cargo world?

cargo.toml is where the dependencies are stored.

5. What is the equivalent of cargo run in the npm world?

npm start is the standard way of running the project using npm, though you have to define this yourself unless you’re using a template like create-react-app. Cargo does it automatically as it knows how the project is structured from cargo new.

1. What are the main similarities between the two?
Cargo and npm are both package managers and they share similar commands in a way.
2. Are there any significant differences?
Cargo is used for building, running and managing rust programs/projects. Npm is used for building, running and managing node.js related projects. npm is used to install packages. Cargo is used to install crates.
3. What is the equivalent of cargo new in the npm world?
npm init is similar to cargo new for initialising new projects.
