海外TECH	DEV Community	Why devs should build with Design Systems	https://dev.to/divriots/why-devs-should-build-with-design-systems-34ck	Why devs should build with Design SystemsDesign systems are now a hot topic among front end teams Design Systems have switched from best in class solutions for big enterprises to must have for any front end team Initially Design Systems have been popularized by designers with tools like Figma Sketch to help them build reusable components to improve their work efficiency and consistency From a developer perspective Design Systems could somehow be compared to Components Libraries as they are widely used as reusable components sources to build web products So why should developers consider building with a Design System on the code side instead Design Systems are not just components libraries They also include design tokens documentation and a design kit Check our article What is a Design System if you want to learn more about this Let s discover some key benefits of building a Design System for developers Workspace for collaborationOne of the most important benefits of working with a Design System is to set up an isolated and collaborative environment to ensure the quality and the adoption of all the assets tokens components documentation designs … that are built and consumed by the team A good Design System platform should provide core features to foster and streamline collaboration within the developer team but also with the whole front end team For instance Backlight offers real time preview and collaboration branch pull request management asynchronous messaging visual reviews … Benefits from design tokensDesign tokens are core elements of the design language used both by designers and developers to build components in Design Systems We can refer to tokens as constants hosting common values in the Design System codebase An interesting thread about it here For instance here are some common tokens colors fonts spacing border radius opacity shadows z index …A Design System is a source of truth for tokens built in collaboration with designers and developers All Design System components built on top of tokens benefit from auto updates when tokens are modified So having a Design System instead of a standalone component library makes it easier and more efficient to build consistent and maintainable components Tips Design system tokens on the code side can be synchronized with the Design System on the design side thanks to some dedicated tools like Specify or built in features in Design System tools like Backlight Benefits from a component library inside a Design SystemComponent Libraries like Material UI have become very popular among developers as they help speed up the development and bring more reusability consistency The challenge of building with component libraries lies in the customization it requires to fit specific design guidelines Building a custom component library inside a Design System either from scratch or on top of a popular component library can have great benefits Design Systems are natively built to offer a nested environment to split the work on components from the work on products Using a Design System can help prevent developers from customizing components directly in production code which could lead to consistency and maintenance issues in the long run Developers are working on components solely in the Design System while consuming components in production code It makes customization of components easier to manage and ensure better quality over time Building and updating the components library in the Design Systems will also benefit from collaboration reviews and testing workflows before being shipped in production code It improves the reliability of new releases and automates components maintenance in production Design Systems are even more powerful when working in cross products or multi brands environments For instance Backlight provides a full environment to work solely on Design Systems with Github Gitlab repository versioning and NPM package publishing features to release bullet proof assets ready to use in production Having the component library inside the Design System also offers the possibility to enhance documentation with live components and playgrounds directly integrated with code snippets from the component library It makes documentation easier to maintain Benefits from design kits inside developer Design SystemA Design System also provides design kits assets brand guidelines brand assets component designs … In a Design System on the developer side a design kit could be a mapping with the Design System on the design side either through links to related design assets Figma Sketch files for instance or with some synchronization provided by design to code code to design features The developer team can benefit from a Design System with such design kits as it will help tackle the handoff issue with designers As the Design System provides design for each component it makes it easy for developers to always have the last related design version at hand Backlight offers the capability to add design links to each component of the Design System Benefits from documentation for developersDocumentation is a core element of a Design System This is a collaborative workspace where the whole front end team shares basics guidelines and how to on the design and code It helps foster collaboration and information sharing across the team Documentation is a powerful tool for developers to find information on how to use design tokens and the component library It s especially useful when onboarding new developers Backlight has built in capability to build collaborative and live documentation from Design System components and tokens ️Boost developers efficiencyAs for designers developers benefit from a great boost of productivity when building products with Design Systems Reusable components from Design Systems help save valuable time from developers each time they need to use components not reinventing the wheel or wasting time finding the right component This study shows for instance that it s faster to build with a Design System instead of building from scratch with also better consistency in the end Lower code maintenanceWorking with a Design System on the developer side also means saving loads of time to ensure product consistency and maintenance When new requirements are coming from the design team like changing a primary color or a component design behavior … it can be quite tedious and time consuming to upgrade all assets in production when not using a Design System On the other hand a Design System offers a collaborative environment to develop components safely by being able to build upgrade and test them in isolation through multiple contexts conditions making later product development and maintenance lighter In Backlight just update your token component create a pull request merge ship an updated npm package and voila all your related components in production are updated automatically No need to waste time maintaining components in production ‍ ️ Better consistencyUsing components from Design Systems will ensure that production components are consistent as the components should be loaded and updated directly from the Design System All similar components are strictly the same and all basic tokens are bound with the Design System ️Better quality and accessibilityQuality and accessibility are key aspects with technical challenges to tackle Building components in a nested environment like in a Design System is a good way to ensure that components are well crafted and tested collaboratively before being safely shipped in production ConclusionBuilding with a Design System can have multiple benefits for developers Eventually the Design System will become a source of truth that is a source of trust for the whole team Design Systems ultimately empower developers with collaboration speed quality and consistency If you want to start playing with Design Systems give a try to one of the starter kits provided by Backlight Many frameworks are supported coming with loads of tokens and components ready to use Perfect for a quick jump in	2022-02-09 09:53:07
海外TECH	DEV Community	The Top 10 Algorithms Every Programmer Should Know In Graph Data Structure!	https://dev.to/rajkousik/the-top-10-algorithms-every-programmer-should-know-in-graph-data-structure-40a5	The Top Algorithms Every Programmer Should Know In Graph Data Structure Why to learn these graph algorithms Graph algorithms are a set of instructions that traverse visits nodes of a graph Some algorithms are used to find a specific node or the path between two given nodes Graphs are very useful data structures which can be to model various problems These algorithms have direct applications on Social Networking sites State Machine modeling and many more I have attached my source code for all the algorithms discussed below You can use it for your referral Breadth First SearchingBreadth First Search is a recursive algorithm for searching all the vertices of a graph or tree data structure Breadth first search is a graph traversal algorithm that starts traversing the graph from the root node and explores all the neighboring nodes Then it selects the nearest node and explores all the unexplored nodes While using BFS for traversal any node in the graph can be considered as the root node An simple algorithm to be remembered for BFS Visit the adjacent unvisited vertex Mark it as visited Display it Insert it in a queue If no adjacent vertex is found remove the first vertex from the queue Repeat Rule and Rule until the queue is empty The Diagrammatic representation of BFS Traversal Reference code Breadth First Searching Depth First SearchingDepth first Search or Depth first traversal is a recursive algorithm for searching all the vertices of a graph or tree data structure Depth First Search DFS algorithm traverses a graph in a depthward motion and uses a stack to remember to get the next vertex to start a search when a dead end occurs in any iteration An simple algorithm to be remembered for DFS Visit the adjacent unvisited vertex Mark it as visited Display it Push it in a stack If no adjacent vertex is found pop up a vertex from the stack It will pop up all the vertices from the stack which do not have adjacent vertices Repeat Rule and Rule until the stack is empty The Diagrammatic representation of DFS Traversal Reference code Depth First Searching Topological SortingTopological sorting for Directed Acyclic Graph DAG is a linear ordering of vertices such that for every directed edge u v vertex u comes before v in the ordering Topological Sorting for a graph is not possible if the graph is not a DAG There can be more than one topological sorting for a graph An simple algorithm to be remembered for Topological sort mark u as visitedfor all vertices v which is adjacent with u do if v is not visited then TopoSort c visited stack donepush u into a stackThe Diagrammatic representation of Topological sortOne of the Topological sort for this graph is gt gt gt gt gt Reference code Topological Sorting Detecting a cycle using Kahn s AlgorithmKahn s topological sort algorithm is cycle detection algorithm which also provides an efficient way to print the topological order Kahn s topological sort algorithm works by finding vertices with no incoming edges and removing all outgoing edges from these vertices Reference code Detecting a cycle using Kahn s Algorithm Dijkstra s AlgorithmDijkstra s algorithm allows us to find the shortest path between any two vertices of a graph It differs from the minimum spanning tree because the shortest distance between two vertices might not include all the vertices of the graph It is a single source shortest path algorithm Here single source means that only one source is given and we have to find the shortest path from the source to all the nodes After applying Dijkstra s Algorithm Reference code Dijkstra s Algorithm Bellman Ford s AlgorithmBellman Ford algorithm helps us find the shortest path from a vertex to all other vertices of a weighted graph It is similar to Dijkstra s algorithm but it can detect graphs in which edges can have negative weight cycles Dijkstra s Algorithm can t able to detect negative weight cycle can give an incorrect result because they can go through a negative weight cycle and reduce the path length Dijkstra doesn t work for Graphs with negative weights Bellman Ford works for such graphs Bellman Ford is also simpler than Dijkstra and suites well for distributed systems The Output Of Bellman Ford s Algorithm Reference code Bellman Ford s Algorithm Floyd Warshall AlgorithmFloyd Warshall Algorithm is an algorithm for finding the shortest path between all the pairs of vertices in a weighted graph This algorithm works for both the directed and undirected weighted graphs But it does not work for the graphs with negative cycles where the sum of the edges in a cycle is negative Here a dynamic programming concept will be used Algorithm Behind Floyd Warshall Algorithm Dij k ←min Dij k Dik k Dkj k Reference code Floyd Warshall Algorithm Prim s AlgorithmPrim s Algorithm is a greedy algorithm that is used to find the minimum spanning tree from a graph Prim s algorithm finds the subset of edges that includes every vertex of the graph such that the sum of the weights of the edges can be minimized An simple algorithm to be remembered for Prim s Algorithm Initialize the minimum spanning tree with a vertex chosen at random Find all the edges that connect the tree to new vertices find the minimum and add it to the tree Keep repeating step until we get a minimum spanning treeOutput Reference code Prim s Algorithm Kruskal s AlgorithmKruskal s Algorithm is used to find the minimum spanning tree for a connected weighted graph The main target of the algorithm is to find the subset of edges by using which we can traverse every vertex of the graph It follows the greedy approach that finds an optimum solution at every stage instead of focusing on a global optimum An simple algorithm to be remembered for Prim s Algorithm First sort all the edges from low weight to high Now take the edge with the lowest weight and add it to the spanning tree If the edge to be added creates a cycle then reject the edge Continue to add the edges until we reach all vertices and a minimum spanning tree is created Reference code Kruskal s Algorithm Kosaraju s AlgorithmIf we can reach every vertex of a component from every other vertex in that component then it is called a Strongly Connected Component SCC Single node is always a SCC The Brute force method will be Floyd Warshall Algorithm But for better time complexity we can use Kosaraju s Algorithm An simple algorithm to be remembered for Prim s Algorithm Perform DFS traversal of the graph Push node to stack before returning Find the transpose graph by reversing the edges Pop nodes one by one from the stack and again to DFS on the modified graph Output Reference code Kosaraju s AlgorithmThese are the most important algorithms one should know as a programmer in graph data structure I will be uploading detailed explanation of each algorithm in upcoming posts
