Packages supported by TinyGo

The following table shows all Go standard library packages and whether they can be imported by TinyGo. If they can’t, you can click the ‘no’ link to jump to the explanation why the package cannot be compiled.

Note that the fact they can be imported, does not mean that all functions and types in the program can be used. For example, sometimes using some functions or types of the package will still trigger compiler errors.

Test results shown are for Linux.
