three.js modify material ( need uniforms )

let uniforms = THREE.UniformsUtils.merge([
  THREE.ShaderLib.standard.uniforms,
  {
    diffuse: { value: new THREE.Color(1, 1, 1) },
    cameraLengthInverse: { value: 0 },
  },
]);
let material = new THREE.ShaderMaterial({
  lights: true,
  vertexColors: true,
  defines: {
    // USE_MAP: true,
  },
  uniforms: uniforms,
  vertexShader: THREE.ShaderLib.standard.vertexShader,
  fragmentShader: THREE.ShaderLib.standard.fragmentShader,
  extensions: {
    derivatives: true, // set to use derivatives
    fragDepth: false, // set to use fragment depth values
    drawBuffers: false, // set to use draw buffers
    shaderTextureLOD: false, // set to use shader texture LOD
  },
});
material.onBeforeCompile = function (shader) {
  shader.vertexShader = shader.vertexShader.replace(
    "void main() {",
    `
      uniform float cameraLengthInverse;
      void main() {
