Some useful snippets created and maintained by Daniel Strong.

Strong Snippets

Exports everything from a file with the same name as the directory it's in.

Useful when you don't want to work inside index files and want clean imports.

Instead of:

`import CoolSnippet from 'components/common/CoolSnippet/CoolSnippet'`

you get:

Instead of:

`import CoolSnippet from 'components/common/CoolSnippet`

Index File Helper

graphql

A starter snippet to quickly create typed mutations.

Depending how you structure your queries/mutations/types, you might want to move the variable and data types to a separate file.

If you like the keep logic close together, consider creating a new file for each mutation.

> Note: The type in your mutations might not be the same as in your typed variables file.

Mutation Typed Starter

Exports the default export from a file with the same name as the directory it's in. 

Useful when you don't want to work inside index files and want clean imports. 

Instead of,

`import CoolSnippet from 'components/common/CoolSnippet/CoolSnippet'`

you get:

The code defines a function called add. The function takes two int arguments and returns an int. The function is defined using type annotations. The first argument, x, is of type int and the second argument, y, is of type int. The function declaration is prefixed with the keyword def. The keyword def tells the compiler that this code is a definition of a function. The next line in the code specifies the function's return type. The return type is int. The return keyword tells the compiler that this function will return an int value. The function definition follows the return keyword. The first line in the function definition defines the function's name. The second line in the function definition defines the function's arguments. The third line in the function definition defines the function's return value. The fourth line in the function definition assigns the value 5 to the variable x and the value 3 to the variable y. The final line in the function definition ends the definition of the add function.
