  • [Tools] VS Code Tips

    Inside one file, you can freely mark the number 1-9:

    shift + cmd + [1-9]

    And jump to Number of bookmark:

    cmd + [1-9]


    It helps to generate type safe interface based the json file you provided.

    For example you can create a json file called pokemon.json:

    {
        "id": 1,
        "name": "Bulbasaur",
        "img": "http://www.serebii.net/pokemongo/pokemon/001.png",
        "type": [ "Grass", "Poison" ],
        "weaknesses": [ "Fire", "Ice", "Flying", "Psychic" ]
    }

    Then in the file you want to generate the code, open vs cammand panel, enter "Paste Json...", enter "Pokemon"...

    It will genearte type safe code and lots of utitlties code.

    export interface Pokemon {
      id:         number;
      name:       string;
      img:        string;
      type:       string[];
      weaknesses: string[];
    }
    
    // Converts JSON strings to/from your types
    // and asserts the results of JSON.parse at runtime
    export namespace Convert {
      export function toPokemon(json: string): Pokemon {
        return cast(JSON.parse(json), r("Pokemon"));
      }
    
      export function pokemonToJson(value: Pokemon): string {
        return JSON.stringify(value, null, 2);
      }
    
      function cast<T>(obj: any, typ: any): T {
        if (!isValid(typ, obj)) {
          throw Error(`Invalid value`);
        }
        return obj;
      }
    
      function isValid(typ: any, val: any): boolean {
        if (typ === "any") { return true; }
        if (typ === null) { return val === null; }
        if (typ === false) { return false; }
        while (typeof typ === "object" && typ.ref !== undefined) {
          typ = typeMap[typ.ref];
        }
        if (Array.isArray(typ)) { return isValidEnum(typ, val); }
        if (typeof typ === "object") {
          return typ.hasOwnProperty("unionMembers") ? isValidUnion(typ.unionMembers, val)
            : typ.hasOwnProperty("arrayItems")    ? isValidArray(typ.arrayItems, val)
            : typ.hasOwnProperty("props")         ? isValidObject(typ.props, typ.additional, val)
            : false;
        }
        return isValidPrimitive(typ, val);
      }
    
      function isValidPrimitive(typ: string, val: any) {
        return typeof typ === typeof val;
      }
    
      function isValidUnion(typs: any[], val: any): boolean {
        // val must validate against one typ in typs
        return typs.some((typ) => isValid(typ, val));
      }
    
      function isValidEnum(cases: string[], val: any): boolean {
        return cases.indexOf(val) !== -1;
      }
    
      function isValidArray(typ: any, val: any): boolean {
        // val must be an array with no invalid elements
        return Array.isArray(val) && val.every((element) => {
          return isValid(typ, element);
        });
      }
    
      function isValidObject(props: { [k: string]: any }, additional: any, val: any): boolean {
        if (val === null || typeof val !== "object" || Array.isArray(val)) {
          return false;
        }
        return Object.getOwnPropertyNames(val).every((key) => {
          const prop = val[key];
          if (Object.prototype.hasOwnProperty.call(props, key)) {
            return isValid(props[key], prop);
          }
          return isValid(additional, prop);
        });
      }
    
      function a(typ: any) {
        return { arrayItems: typ };
      }
    
      function u(...typs: any[]) {
        return { unionMembers: typs };
      }
    
      function o(props: { [k: string]: any }, additional: any) {
        return { props, additional };
      }
    
      function m(additional: any) {
        return { props: {}, additional };
      }
    
      function r(name: string) {
        return { ref: name };
      }
    
      const typeMap: any = {
        "Pokemon": o({
          id: 0,
          name: "",
          img: "",
          type: a(""),
          weaknesses: a(""),
        }, false),
      };
    }
    

      

    A easy way to dealing with Git.

    Good for demoing the code in a team.
