# Major CLI Versions - Notable Changes (WIP)

## npm v7

#### Timeline:
- **Generally Available:** January 2021
- **End-of-Life:** October 2021(?)

#### Features:
- [x] Install Peer-Depedendencies by Default
- [ ] `npm install` throws an error when trying to install a version of itself when there's an `engine` mismatch

## npm v8

#### Timeline:
- **Alpha:** August 2021
- **Generally Available:** September 2021

### Goals
- Low friction from `7 -> 8`
- Reduce maintenance burden
- Align release schedules better with Node Project
- Update deps which are dropping support for unsupported nodes

### Breaking Changes
- Drop support for `node@10`
- Drop programmatic API (ie. no more `require('npm')`)
- Re-think the dist-tags we use
- THAT'S IT.

#### Bikeshedding:
- Should we provide a maintenance window for `v7`?

## npm v9 - Early 2022

### Goals
- Standardize reasonable defaults
- Support complex workflows

### Features
- **Big Change**: refactor `config` layer entirely
- unknown config keys or invalid config values will crash the process
- use a cli args parser that is simpler and more well-supported than nopt
- get rid of side-effecty boolean collections (`--save-dev`, `--save-peer`, etc.)
- get rid of nerf-dart and `@scope:registry` cleverness
- support registry-specific, scope-specific, and command-specific configs in an organized manner
- consider move to json instead of ini (there are many trade-offs here, we should enumerate them and make a decision -- note: "you can nest objects in json" is not a consideration, ini can do this as well)
- **Medium Change**: rethink `npm link`
- What are the jobs to be done by this command?
- How do users _expect_ it to behave in various scenarios?
- Given that, design an implementation that meets the user needs optimally.
- No commitments at this time to implementation direction.
- **Feature**: Differentiate "scripts" from "lifecycle events"
- needs RFC
- Something like this:

        {
          "name": "my-app",
          "version": "1.0.0",
          "events": {
            "install": "npm run build"
          },
          "scripts": {
            "build": "node build.js"
          }
        }

- `"events"` defaults to running the appropriate thing from `scripts` for backwards compatibility (possibly with a deprecation notice?)
- if `"events"` contains an unknown key, we crash
- `"events"` may not be executed explicitly via `run-script`, only scripts can be.
- `"events"` value may be an array of script names to run?

        {
          "events": {
            "preinstall": ["build:css", "build:js", "build:html"]
          },
          "scripts": {
            "build:css": "etc",
            ...
          }
        }

- **Remove** `npm set-script`
- New command: `npm add`
- @isaacs: this is just "npm install but fails if no positional args", correct?
- New command: `npm adduser` (alias, `register`)
- New command: `npm workspace` (alias, `ws`)
- `npm ws add ./foo` === `npm init -w foo` + `cd foo/ && echo "workspace-root=../" > .npmrc`
- `npm ws remove ./foo` === `rm -rf ./foo`
- `npm update` supports saving back to `package.json` via `--save`
- `npm doctor` refactor
- Workspace & Run Script Concurrance
- `--concurrently` flag introduced to `npm run` & `-w` or `-ws`
- Workspace alias'
- `npm ws alias <name> <path>`
- Workspace & Run Script Groups
- `npm run build`
- `npm run build -ws internal`
- Reevaluate package-init default bin entry behavior

{
    "scripts": {
        "build:css": "...",
        "build:js": "...",
        "build:html": "..."
    },
    "workspace": {
        "internal:tools": "./internal/tools",
        "internal:server": "./internal/server"
    }
}

##### `package.json`

{
    "name": "pkg",
    "version": "1.0.0",
    "npm": {
        "commands": {
            "install": {
                "save": true
            }
        }
    }    
}

- New Context Config Mappings
- `--local` maps to `--location=local`
- `--user` maps to `--location=user`
- `--remote` maps to `--location=remote`
- `--global` maps to `--location=global`
- Auth w/ GitHub (ready when it is)
- New Exec Commands
- `npm exec [list|add|remove]`

### Notable Breaking Changes
- `npm add` is no longer an alias to `npm install`
- `npm adduser` is no longer an alias to `npm login`
- `npm login` is no longer an alias to `npm adduser`
- `--local` no longer maps to `--no-global`
- `npm config` defaults to modify the `local` `--location` by default
- `auth-type` removed
- `node-gyp` update to latest

## npm v10
- uses `strict` mode by default
- New `npm link` experience
