Description

Technical Field

[0001] The present application relates to the field of blockchain technology, and in particular to the construction and device, equipment, and storage medium of an online IDE for developing smart contracts. Background Art

[0002] There are currently two smart contract development solutions:

[0003] The first is to write and debug smart contract code in the desktop IDE (Integrated Development Environment, which is an application that provides a program development environment). However, before that, developers are required to download IDE tools. For example, to develop a Solidity contract, developers need to install the Solidity language plug-in, and to develop a Go contract, developers need to install the Go language plug-in. In addition, developers also need to configure environment variables for different development languages. Completing this series of processes often requires a lot of effort and time from developers. Therefore, this development solution is cumbersome and brings a very bad development experience to developers, especially novices.

[0004] The second is to write and debug smart contract code on an online IDE. Currently, the most popular one is RemixIDE launched by Ethereum. Remix IDE integrates Solidity language support and various tools for compilation, deployment and debugging, which developers can use out of the box. However, it currently only supports Solidity language, and it does not support functions such as reference jump and file search in the code. In other words, it does not have the development functions commonly used by desktop IDEs, and is not very friendly to the development of complex smart contracts. Summary of the invention

[0005] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a method and device, equipment, and storage medium for building a smart contract development system.

[0006] In a first aspect, the present application provides a method for building an online IDE for developing smart contracts, including: setting the front-end interactive interface of the online IDE through a first preset extension module of the Theia framework.

[0007] In the second aspect, the present application provides a device for building an online IDE for developing smart contracts, including: an interface setting module, used to set the front-end interactive interface of the online IDE through a first preset extension module of the Theia framework.

[0008] In a third aspect, the present application provides a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the above method when executing the computer program.

[0009] In a fourth aspect, the present application provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program implements the steps of the above method when executed by a processor.

[0010] In the method provided in this embodiment, the front-end interactive interface of the online IDE is set by the first preset extension module of the Theia framework. This application uses the extension module in the Theia framework to build the front-end interactive interface of the online IDE, and the setting process is simple and convenient. Moreover, since the bottom layer of the Theia framework reuses a lot of development tool code modules and interfaces, etc., functions such as code jump and file search are functions supported by the Theia framework itself, so the embodiment of the present application can provide a development experience similar to the desktop IDE. Before using the Theia framework to build an online IDE, various language plug-ins (such as Go plug-ins, Solidity plug-ins, Java plug-ins) and environment variables are configured, so when using the online IDE built based on the Theia framework to develop smart contracts, it is not necessary to install various language plug-ins and configure environment variables, so the development process of smart contracts is relatively simple, which can bring a good development experience to developers.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0016] Figure 1 A method for building an online IDE for developing smart contracts provided in an embodiment of the present application is as follows: Figure 1 As shown, the method comprises the following steps:

[0017] S100. Setting the front-end interactive interface of the online IDE through a first preset extension module of the Theia framework.

[0018] Understandably, a smart contract is a computer protocol designed to communicate, verify or execute contracts in an information-based manner. Smart contracts allow for trusted transactions without a third party, which are traceable and irreversible. The purpose of smart contracts is to provide a security method that is superior to traditional contracts and reduce other transaction costs associated with contracts.

[0019] It is understandable that online IDE is an online integrated development environment. As long as there is an Internet connection, users can open a browser, log in to the online IDE through the browser, and write code anytime and anywhere.

[0020] Understandably, Theia framework is an extensible platform based on modern web technologies for developing mature, multi-language cloud computing and desktop products. Theia framework has many extensions, and each extension includes many extension modules, each of which is provided to Theia framework in the form of NPM packages, which is the package manager under the running environment Node.js.

[0021] It is understandable that, as an open source framework, Theia framework can form an online IDE application by deploying and setting its extension modules. The main framework of this application is the front-end module and the back-end module. The front-end module is mainly responsible for the browser part, and the back-end module is mainly responsible for the server part. The setting of the front-end interactive interface and the communication method between the front-end and back-end modules are all important components of building an online IDE. In step S100, the configuration of the various contents constituting the front-end interactive interface is realized through the first preset extension module of the Theia framework, that is, the front-end interactive interface of the online IDE can be obtained.

[0022] It is understandable that when developing smart contracts using the front-end interactive interface, it is necessary to use the various submenus on the front-end interactive interface. These submenus are some of the commonly used functions when developing smart contracts, such as compilation, deployment, calling, debugging, etc. Therefore, it is necessary to set the submenus on the front-end interactive interface.

[0023] In specific implementation, the first preset extension module used in submenu setting may include a menu extension module and a command extension module, wherein the menu extension module is an extension module of the menu extension type, in which the registration information of multiple submenus required for developing smart contracts (for example, the name, location, order, etc. of the submenus) may be defined or set, and after the registration information is set in the menu extension module, it may be used to implement the display of each submenu. The command extension module is an extension module of the command extension type, in which the execution command of the submenu may be defined or set, and after the execution command of the submenu is set in the command extension module, after the submenu is triggered, the submenu may execute the corresponding command and complete the corresponding interactive action. For example, clicking a button corresponding to a submenu will pop up a corresponding window, etc. In other words, step S100 may specifically include:

[0024] S101. Writing business codes for displaying multiple preset submenus in the menu bar required for developing smart contracts in the menu extension module, and writing business codes corresponding to execution commands of the preset submenus in the command extension module;

[0025] It is understandable that there are multiple submenus under the menu bar, and one submenu can implement one or more corresponding functions, such as compile, deploy, call, and debug.

[0026] It is understandable that since the simple basic information such as the name, position, and order of each submenu can be defined in the menu extension module, the relevant registration information of each submenu is written in the menu extension module. After the writing is complete, it can be used to realize the display of each submenu, that is, each submenu can be seen on the front-end interactive interface, but at this time each submenu cannot have its due functions.

[0027] It is understandable that, since the execution command of each submenu can be set in the command extension module, the so-called execution command can include instructions for actions that the submenu needs to perform in order to complete its functions.

[0028] For example, see the following code snippet:

[0029]

[0030]

[0031] In the above code segment, we first define the deployment of this submenu, such as the basic information of the submenu, such as the title, label, icon class, etc., and then write the form code for deploying this submenu. The form code is used to pop up the form page corresponding to the submenu when the user clicks the corresponding submenu in the menu bar, so that the user can further configure the submenu in the form page.

[0032] S102, triggering a corresponding button of a preset submenu in the menu bar, popping up a form page corresponding to the preset submenu, wherein the form page is a configuration page of the preset submenu;

[0033] It is understandable that a form page is a React component, and React is a JavaScript library for building user interfaces. The specific information of the submenu can be configured in the form page.

[0034] S103. When the configuration information corresponding to the preset submenu is received through the form page, the business code corresponding to the configuration information is injected into the context of the Theia framework.

[0035] It is understandable that, since the configuration information entered in the form page is not a business code, it is necessary to convert the configuration information into a business code and inject it into the context of the Theia framework. When a submenu is needed, the business code corresponding to the configuration information can be called from the Theia framework. The content written in the menu extension module and the command extension module is the business code itself. The menu extension module and the command extension module are bound to the container module in the Theia framework, so the business code in the menu extension module and the command extension module can also be called when using the submenu, thereby realizing the corresponding function of the submenu.

[0036] In specific implementation, S103 may specifically include: when the configuration information corresponding to the preset submenu is received through the form page, the business code corresponding to the configuration information is written in a preset programming language, and the business code corresponding to the configuration information is injected into the context of the Theia framework using a preset decorator.

[0037] The preset programming language can be selected as needed, for example, Typescript language. The preset decorator can be selected as needed, for example, injectable decorator. Specifically, the business code developed in Typescript language can be injected into the context of the Theia framework by using the injectable decorator through Inversify.js. Inversify.js is a powerful lightweight IoC container framework. Inversify implements the IoC container through the dependency injection mode.

[0038] In specific implementation, the method provided in the embodiment of the present application may also include the following steps:

[0039] S200. Set the path of the business code file of the back-end module in the description file of the second preset extension module of the Theia framework; the path is used for loading the business code in the business code file according to the path when the website server corresponding to the back-end module is started, so as to realize the operation of the back-end module; the website server provides the Node.js operating environment for the back-end module.

[0040] It is understandable that although the business codes of the front-end module and the back-end module are deployed together and are both in the Theia framework, their execution environments are different. The front-end module is the part that users see, and its execution environment is in the browser, while the execution environment of the back-end module is on the server and runs on the Node.js environment. When users access the online IDE through the URL, a web server, i.e. a website server, is required. The website server can provide the Node.js operating environment for the back-end module. Specifically, Express can be used as the HTTP server. Express is the Node.js Web application development framework, and Node.js is JavaScript running on the server.

[0041] In specific implementation, not only can the path of the business code file of the back-end module be set in the description file of the second preset extension module, but the path of the business code file of the front-end module can also be set in the description file of the second preset extension module. In this way, when the browser is started, the business code in the business code file of the front-end module can also be called according to the specific path to realize the operation of the front-end module.

[0042] It is understandable that each extension contains a description file - package.json file, which can contain several key fields, as shown in the following code snippet:

[0043]

[0044] In the above code snippet, the first keyword "theia-extension" marks the NPM package as an extension. When the Theia framework starts, it will traverse all NPM packages and mark all NPM packages as an extension. The second keyword "theiaExtensions" is to enumerate all modules in this extension. Each module is the entry point of the extension. Among them, the field "frontend" represents the entry point of the front-end module, and the storage path of the business code file of the front-end module can be set in this field. "backend" represents the entry point of the back-end module, and the storage path of the business code file of the back-end module can be set in this field.

[0045] It is understandable that the first preset extension module and the second preset extension module are both modules in one extension, and the description file of the second preset extension module is the description file of the extension to which the second preset extension module belongs.

[0046] It is understandable that by defining the path of the business code file of the front-end module and / or back-end module in the description file, the corresponding business code can be called when the browser and / or server is started, thereby realizing the operation of the front-end module and / or back-end module.

[0047] In specific implementation, the method provided in the embodiment of the present application may also include the following steps:

[0048] S300, establishing a communication mechanism between the front-end module and the back-end module.

[0049] It is understandable that since the front-end module runs on the browser and the back-end module runs on the server, data communication is required between the browser and the server when developing a smart contract. The communication mechanism in step S300 is used to achieve communication between the two.

[0050] In specific implementation, the above step S300 may specifically include the following steps:

[0051] S301, setting an externally exposed backend service interface on the backend module, setting the business code of the backend service interface, and injecting the business code of the backend service interface into the context of the Theia framework;

[0052] It is understandable that the externally exposed interface refers to the interface that others can reference and call. In this step, a backend service interface is defined, and the corresponding interface file contains various methods, such as smart contract compilation method, smart contract deployment method, smart contract calling method, etc. See the following code segment, which is used to define the backend service interface:

[0053]

[0054] The above code first defines the backend service interface, and then declares the corresponding compilation method, etc., thereby realizing the setting of a backend service interface.

[0055] It is understandable that setting the business code of the backend service interface is to implement an instance of the backend service interface. Referring to the following code segment, an instance of the backend service interface ContractBackendService can be implemented:

[0056]

[0057]

[0058] After setting up the instance of the backend service interface, you can inject the business code into the Theia framework context. Specifically, you can use a preset decorator to inject the business code of the backend service interface into the context of the Theia framework and bind it to the dependency injection container of the Theia framework. For example, use the injectable decorator through Inversify.js to inject the business code into the context of the Theia framework.

[0059] S302. Set a front-end service interface with the same definition name as the back-end service interface on the front-end module, and inject the business code of the back-end service interface into the context of the Theia framework; wherein the front-end service interface and the back-end service interface are used to realize the communication between the front-end module and the back-end module through a preset communication protocol when developing a smart contract.

[0060] It is understandable that a front-end service interface with the same name as the back-end service interface is set on the front-end module here in order to use the instance of the back-end service interface more directly and conveniently without having to set up the instance again, that is, directly inject the business code of the back-end service interface as the business code of the front-end service interface into the context of the Theia framework.

[0061] See the following code snippet:

[0062]

[0063] The above code segment introduces how the front-end module calls the business code of the back-end service interface after registering the back-end service interface and the corresponding business code. Specifically, it first establishes a websocket communication connection and returns an instance of the back-end service interface.

[0064] In the specific implementation, the business code of the backend service interface is injected into the context of the Theia framework in this step, which may specifically include: injecting the business code of the backend service interface into the context of the Theia framework using a preset decorator, and binding it to the dependency injection container of the Theia framework. For example, the business code is injected into the context of the Theia framework using the injectable decorator through Inversify.js.

[0065] It is understandable that when developing a smart contract, the front-end service interface of the front-end module and the back-end service interface of the back-end module communicate with each other, so as to realize the communication between the front-end module and the back-end module, that is, the communication between the browser and the server.

[0066] The preset communication protocol may adopt the JSON-RPC protocol, which is a stateless and lightweight remote procedure call (RPC) transmission protocol, and its transmission content is mainly through JSON. In this way, the front-end and back-end modules can communicate through JSON-RPC on the websocket.

The present application uses the extension module in the Theia framework to build the front-end interactive interface of the online IDE, and the setting process is simple and convenient. Moreover, since the bottom layer of the Theia framework reuses a lot of development tool code modules and interfaces, etc., functions such as code jump and file search are functions supported by the Theia framework itself, so the embodiment of the present application can provide a development experience similar to the desktop IDE. Because before using the Theia framework to build an online IDE, various language plug-ins (such as Go plug-ins, Solidity plug-ins, Java plug-ins) and environment variables are configured, so when using the online IDE built based on the Theia framework to develop smart contracts, it is not necessary to install various language plug-ins and configure environment variables, so the development process of smart contracts is relatively simple, which can bring a good development experience to developers.
