It seems just jquery is required, but package.json contains a lot of others.

“dependencies”: { “broccoli-funnel”: “^2.0.1”, “broccoli-merge-trees”: “^2.0.0”, “chalk”: “^2.3.0”, “ember-cli-get-component-path-option”: “^1.0.0”, “ember-cli-is-package-missing”: “^1.0.0”, “ember-cli-normalize-entity-name”: “^1.0.0”, “ember-cli-path-utils”: “^1.0.0”, “ember-cli-string-utils”: “^1.1.0”, “ember-cli-valid-component-name”: “^1.0.0”, “ember-cli-version-checker”: “^2.1.0”, “ember-router-generator”: “^1.2.3”, “inflection”: “^1.12.0”, “jquery”: “^3.3.1”, “resolve”: “^1.6.0” },

I’m not going to use ember-cli and if I do “npm install ember-source --save-dev”, many packages are installed with ember-source and jquery.

- ember-source@3.1.2 added 63 packages in 4.109s

Using ember-source without using ember-cli is not a supported path (as of Ember 3.0.0).

It is absolutely possible to use Ember without jQuery. There is still some amount of work to do to implement [this RFC](https://github.com/emberjs/rfcs/blob/master/text/0294-optional-jquery.md), but the work arounds mentioned in the RFC are functional.

All of these packages are actually used when ember-source is consumed. Some are used by the blueprints (e.g. to support things like `ember generate route posts`), others are used for the build system, and others still are used to detect which version of other collaborating packages are in use (so that ember-source can work properly with them).

I’m able to build a simple ember 3.0 app just by using webpack and not involving ember-cli stuff.

Is it better to place those packages except jquery into devDependencies and place jquery into optDependencies?

This would be hugely inconvenient for the 99.99% of Ember users who are using ember-cli. They _aren’t_ devDependencies. Apps that add ember-source need those packages. And they need specific matching versions of them.

Your custom setup is almost certainly broken for a large number of possible addons. If you want to package your app with webpack, that is actually already supported on the current master version of ember-cli via the [packager hook](https://github.com/ember-cli/rfcs/blob/567201627bcc6baa2d70103bd5b6f9e23e8ea0d9/active/0051-packaging.md).
