how to create an outline shader?

Depends on where you want the outlines really. Outline shaders come in many varieties.

[hammouda101010]

a toon shader, like this:

[David-Orangemoon]

Here is a simple 2d one

uniform highp vec3 outline_c;
uniform highp float progress;

void fragment() {
  fragColor = mix(fragColor, vec4(outline_c,fragColor.a), progress - fragColor.a * progress);
}

Here is a simple glsl implementation of an outline.
