            How to make tsyringe (dep injection lib) resolve classes that have dependencies?
            Asked 2022-Feb-08 at 18:36

            I am clearly misunderstanding how TSyringe is supposed to resolve classes with dependencies.

            I created a minimal repro. In my index.tsx, I do as they indicate in the docs and import reflect-metadata. This example works if I inject a singleton class with no dependencies:

            ANSWER

            Answered 2022-Feb-08 at 18:36

            OK so I figured this out.

            To keep the typescript metadata and allow reflect-metadata to do its thing, we need to add babel-plugin-transform-typescript-metadata to the project.

            However, in order to customize create-react-app, you need the craco library. There are several out there, but craco is the only one I could that supports CRA 4.x. You cannot be on the latest (CRA 5.0) as none of these libs support it yet.

            So:

            1 - Install Craco and set it up.

            2 - Install babel-plugin-transform-typescript-metadata as a dev dependency

            3 - Add a craco.config.js file to your project to load this plugin:

            You should be using callThrough instead of stub. When you stub it won't call the actual implementation and basically just ignore the call. Check out Method stubs for more info.

            When you use callThrough it would call the actual implementation thus adding coverage. So you can use something like:

            React with TypeScript using tsyringe for dependency injection
            Asked 2021-May-19 at 13:12

            I am currently having trouble with my React TypeScript project.

            I created my project with npx create-react-app my-app --template typescript.

            I recently added tsyringe for dependency injection and was trying to implement it for an apiService.

I already add experimentalDecorators and emitDecoratorMetadata to my tsconfig.json file with no success.

            React-Scripts manages many of the configs related to the project. For many cases, this is fine and actually a nice feature. However, because React-Scripts uses Babel for it's development environment and does not expose the config.

            You have to run npm run eject to expose the configurations.

            Please note, this is a one-way operation and can not be undone. Personally, I prefer more control with my configuration.

            After this you can edit the webpack.config.js in the newly created config folder.

            Find the section related to the babel-loader in the dev-environment and add 'babel-plugin-transform-typescript-metadata' to the plugins array.

            Absolutely not.

            Don't confuse types (interfaces, types, enums, etc) with values (boolean, string, object, array, function, etc).

            Values can be arguments and each value has a type but an argument cannot be a type.

            Since OperationSub isn’t used anywhere, it cannot affect injected Operation value.

            Calculators with different dependency sets should be represented with multiple containers. Summing calculator can be considered a default implementation and use root container, or both implementations can be represented by children containers while root container remains abstract.
