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 are for linux/amd64.
Some tests are skipped because they use functionality that TinyGo does not implement. Some packages are also tested with a larger stack than the default. This is the same procedure that the TinyGo CI uses. These are the skipped tests.
