the change about mainTemplate

[lanmch]

As the webpack5 docs, some mainTemplate hooks has been removed. But in my project with webpack4, we use the mainTemplate.hooks.bootstrap and mainTemplate.hooks.requireEnsure to inject some js to the final file. But now the mainTemplate feature is not exist, and the webpack5 docs now show how to change it. And from the webpack5 source code, I cant find any new hooks.

my plugin code

 apply(compiler) {
    if (compiler.hooks) {
      compiler.hooks.compilation.tap('RetryPluguin', compilation => {
        compilation.mainTemplate.hooks.bootstrap.tap(
          'RetryPluginAddCustomLogic',
          (source, chunk, hash, moduleIdExpression) => {
            const flagName = JSON.stringify(`__manifest_executed_${chunk.ids.join('_')}_${hash}__`);
            const newSource = makeTagRetry(source, ensureExecOnceToBeInject, getExecOnceExecScript(flagName));
            return newSource;
          },
        );
        compilation.mainTemplate.hooks.requireEnsure.tap(
          'RetryPluginAddCustomLogic',
          (source, chunk, hash, moduleIdExpression) => {
            let newSource = source;
            console.log('source: ', source); // nothing
            newSource = makeTagRetry(newSource, scriptToBeInject, scriptRetry);
            newSource = makeTagRetry(newSource, linkToBeInject, cssRetry);
            return newSource;
          },
        );
      });
    }
  }

Do you just need inject custom code or modify webpack runtime?

[alexander-akait]

We still support them in webpack v5 https://github.com/webpack/webpack/blob/main/lib/RuntimePlugin.js#L367

Also runtime logic you can find here https://github.com/webpack/webpack/blob/main/lib/RuntimePlugin.js#L367

I know it and I find this file. As what i said below, i try to use this hooks compilation.hooks.runtimeRequirementInTree , but i am not sure it is a right way to disable it.

I try to cover the define of webpack_require.l and rewrite it.
