html-oriented manifest format ----------------------------- In the new schema format, which is defined in ember-fastboot/fastboot@3fd5bc9 the manifest is written into HTML and later extracted by fastboot on server side instead of previously reading from dist/package.json Note: The new schema in fastboot does not handle fastboot config https://github.com/ember-fastboot/ember-cli-fastboot/tree/e4d0b7c7bcdf82def0dc8726835b49d707673f41#providing-additional-config This commit changes to read Fastboot.config from dist/package.json instead of ignoring it Allow to require module path from whitelisted dependency ------------------------------------------------------- Incrementing schema to 5 also included the changes in schema 4 strictWhitelist See ember-fastboot/fastboot#200 Revert back to put config in dist/package.json add data-fastboot-ignore to unexpected files properly ignore files that should not execute in fastboot
