Public API: Create new project (fixes #1095) (#1106) * Converts import script to use public API endpoints The endpoints don't exist yet, but this is a good way to see how the implementation of the data structures differ. * Exposes public API endpoint to fetch user's sketches * Implements public API delete endpoint * Adds helper to create custom ApplicationError classes * Adds create project endpoint that understand API's data structure This transforms the nested tree of file data into a mongoose Project model * Returns '201 Created' to match API spec * Removes 'CustomError' variable assignment as it shows up in test output * transformFiles will return file validation errors * Tests API project controller * Tests toModel() * Creates default files if no root-level .html file is provided * Do not auto-generate a slug if it is provided Fixes a bug where the slug was auto-generated using the sketch name, even if a slug property had been provided. * Validates uniqueness of slugs for projects created by the public API * Adds tests for slug uniqueness * Configures node's Promise implementation for mongoose (fixes warnings) * Moves createProject tests to match controller location * Adds support for code to ApplicationErrors * deleteProject controller tests * getProjectsForUser controller tests - implements tests - update apiKey tests to use new User mocks * Ensure error objects have consistent property names `message` is used as a high-level description of the errors `detail` is optional and has an plain language explanation of the individual errors `errors` is an array of each individual problem from `detail` in a machine-readable format * Assert environment variables are provided at script start * Version public API * Expect "files" property to always be provided * Fixes linting error * Converts import script to use public API endpoints The endpoints don't exist yet, but this is a good way to see how the implementation of the data structures differ. * Exposes public API endpoint to fetch user's sketches * Implements public API delete endpoint * Adds helper to create custom ApplicationError classes * Adds create project endpoint that understand API's data structure This transforms the nested tree of file data into a mongoose Project model * Returns '201 Created' to match API spec * Removes 'CustomError' variable assignment as it shows up in test output * transformFiles will return file validation errors * Tests API project controller * Tests toModel() * Creates default files if no root-level .html file is provided * Do not auto-generate a slug if it is provided Fixes a bug where the slug was auto-generated using the sketch name, even if a slug property had been provided. * Validates uniqueness of slugs for projects created by the public API * Adds tests for slug uniqueness * Configures node's Promise implementation for mongoose (fixes warnings) * Moves createProject tests to match controller location * deleteProject controller tests * Adds support for code to ApplicationErrors * getProjectsForUser controller tests - implements tests - update apiKey tests to use new User mocks * Ensure error objects have consistent property names `message` is used as a high-level description of the errors `detail` is optional and has an plain language explanation of the individual errors `errors` is an array of each individual problem from `detail` in a machine-readable format * Assert environment variables are provided at script start * Version public API * Expect "files" property to always be provided * Fixes linting error * Checks that authenticated user has permission to create under this namespace Previously, the project was always created under the authenticated user's namespace, but this not obvious behaviour.
