tsconfig.json

Therefore, some options need to configured carefully to make the IDE’s inspection function consistent with the compilation behavior in Cocos Creator.

The following options should not be modified explicitly:

For example, if tsconfig.json is set to:

However, the implied in Creator is es2015, therefore it may prompt errors such as “require undefined” at runtime.

The following script code is legal for Creator, but the IDE may report an error. This is because compilerOptions.target is set to es5, while Set was introduced in ES6.

It is also possible to freely modify options.

Set compilerOptions.noImplicitAny to true in tsconfig.json, as using an IDE (such as Visual Studio Code), the corresponding error prompt will be received.

For most projects, some options in are fixed. For example, compilerOptions.target, compilerOptions.module and Cocos Creator type declarations, file location, etc.

Due to the good design of tsc, the extends option allows tsconfig.json to be cascadable. Cocos Creator supports this, therefore, the fixed tsconfig option is placed under {project path}/tmp/tsconfig.cocos.json and managed by Cocos Creator.

Fortunately, Creator will automatically generate such a file when creating a new project.
