* Support for multiple source paths via package.json srcPaths entry. Initial support for yarn workspace. Support lerna workspace, fix for when to use template files. Remove support for specifying srcPaths in package.json. Re-enable transpilation caching. * Clean up, use file matching (similar to original) in webpack configs instead of matching function. * Remove package lock files. * Fix for eject. Note: monorepos won't work after eject. Can be fixed easily with JEST 22.0.?+ which has file pattern matches against realpaths. * Filter tests to run only tests in monorepo components included by the app. (Not sure this is desireable, might be cool to be able to easily run all tests in monorepo from one app.) * Fix conditions for when to use template. * Fix eject. * Remove code that is not needed w/ Jest 22. * Include all cra-comp tests in monorepo instead of trying to include only tests that are dependencies of app. (tests can be easily filtered via jest cli if desired, e.g. 'npm test -- myapp comp1') * Pin find-pkg version. * Hopefully fix jest test file matching on windows by removing first slash. * E2E tests for monorepo. * Run monorepo tests in CI. * Fix and test post-eject build. * Fix e2e test. * Fix test suite names in appveyor. * Include individual package dirs as srcPaths instead of top-level monorepo root. Fixes build/start after eject. * Fix running tests after eject. * Clean up test workspace, add some verifcations. * Cleanup. * Try to fix hang when running test on appveyor. * Don't write babel or lint config to package.json when ejecting. * Incorporate review comments. * Simply monorepo pkg finder * Only include monorepo pkgs if app itself is included in monorepo * Check for specific tests in e2e * Fixes for windows. * Fix for kitchensink mocha tests compiling. * Add lerna monorepo test. * Fix lerna bootstrap on windows. * Incorporate more review comments: * remove support for lerna w/o yarn workspace * add react and react-dom as devDeps to comp1 and comp2 * Add monorepo info to user guide.
